# Docker Hub Quick Start Guide
## 🚀 Quick Setup (3 Steps)
### 1. Create Docker Hub Secrets
```bash
./infrastructure/kubernetes/setup-dockerhub-secrets.sh
```
This creates the `dockerhub-creds` secret in all namespaces with your Docker Hub credentials.
### 2. Apply Updated Manifests
```bash
# Development environment
kubectl apply -k infrastructure/kubernetes/overlays/dev
# Production environment
kubectl apply -k infrastructure/kubernetes/overlays/prod
```
### 3. Verify Pods Are Running
```bash
kubectl get pods -n bakery-ia
```
All pods should now be able to pull images from Docker Hub!

## 🔧 What Was Configured
✅ **Docker Hub Credentials**
- Username: `uals`
- Access Token: `dckr_pat_zzEY5Q58x1S0puraIoKEtbpue3A`
- Email: `ualfaro@gmail.com`
✅ **Kubernetes Secrets**
- Created in: `bakery-ia`, `bakery-ia-dev`, `bakery-ia-prod`, `default`
- Secret name: `dockerhub-creds`
✅ **Manifests Updated (47 files)**
- All service deployments
- All database deployments
- All migration jobs
- All cronjobs and standalone jobs
✅ **Tiltfile Configuration**

```bash
export USE_DOCKERHUB=true
export DOCKERHUB_USERNAME=uals
docker login -u uals
tilt up
```
---
## 🐳 Pushing Images to Docker Hub
```bash
# Login first
docker login -u uals
# Use the automated script
./scripts/tag-and-push-images.sh
```
---
## ⚠️ Troubleshooting
**Problem: ImagePullBackOff**
```bash
# Check if secret exists
kubectl get secret dockerhub-creds -n bakery-ia
# Recreate secret if needed
./infrastructure/kubernetes/setup-dockerhub-secrets.sh
```
**Problem: Pods not using new credentials**
```bash
# Restart deployment
kubectl rollout restart deployment/<deployment-name> -n bakery-ia
```
---
## 📝 Scripts Reference
| Script | Purpose |
|--------|---------|
| `infrastructure/kubernetes/setup-dockerhub-secrets.sh` | Create Docker Hub secrets in all namespaces |
| `infrastructure/kubernetes/add-image-pull-secrets.sh` | Add imagePullSecrets to manifests (already done) |
| `scripts/tag-and-push-images.sh` | Tag and push all custom images to Docker Hub |

# Database Monitoring with SigNoz
This guide explains how to collect metrics and logs from PostgreSQL, Redis, and RabbitMQ databases and send them to SigNoz.
## Table of Contents
1. [Overview](#overview)
2. [PostgreSQL Monitoring](#postgresql-monitoring)
3. [Redis Monitoring](#redis-monitoring)
4. [RabbitMQ Monitoring](#rabbitmq-monitoring)
5. [Database Logs Export](#database-logs-export)
6. [Dashboard Examples](#dashboard-examples)
## Overview
**Database monitoring provides:**
- **Metrics**: Connection pools, query performance, cache hit rates, disk usage
- **Logs**: Query logs, error logs, slow query logs
- **Correlation**: Link database metrics with application traces
**Three approaches for database monitoring:**
1. **OpenTelemetry Collector Receivers** (Recommended)
- Deploy OTel collector as sidecar or separate deployment
- Scrape database metrics and forward to SigNoz
- No code changes needed
2. **Application-Level Instrumentation** (Already Implemented)
- Use OpenTelemetry auto-instrumentation in your services
- Captures database queries as spans in traces
- Shows query duration, errors in application context
3. **Database Exporters** (Advanced)
- Dedicated exporters (postgres_exporter, redis_exporter)
- More detailed database-specific metrics
- Requires additional deployment
## PostgreSQL Monitoring
### Option 1: OpenTelemetry Collector with PostgreSQL Receiver (Recommended)
Deploy an OpenTelemetry collector instance to scrape PostgreSQL metrics.
#### Step 1: Create PostgreSQL Monitoring User
```sql
-- Create monitoring user with read-only access
CREATE USER otel_monitor WITH PASSWORD 'your-secure-password';
GRANT pg_monitor TO otel_monitor;
GRANT CONNECT ON DATABASE your_database TO otel_monitor;
```
#### Step 2: Deploy OTel Collector for PostgreSQL
Create a dedicated collector deployment:
```yaml
# infrastructure/kubernetes/base/monitoring/postgres-otel-collector.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: postgres-otel-collector
namespace: bakery-ia
labels:
app: postgres-otel-collector
spec:
replicas: 1

volumeMounts:
- name: config
mountPath: /etc/otel-collector

service:
pipelines:
metrics:
receivers: [postgresql/auth, postgresql/inventory]
processors: [memory_limiter, resource, batch, resourcedetection]

```
#### Step 3: Create Secrets
```bash
# Create secret for monitoring user password
kubectl create secret generic postgres-monitor-secrets \
-n bakery-ia \
--from-literal=POSTGRES_MONITOR_PASSWORD='your-secure-password'
```
#### Step 4: Deploy
```bash
kubectl apply -f infrastructure/kubernetes/base/monitoring/postgres-otel-collector.yaml
```
### Option 2: Application-Level Database Metrics (Already Implemented)
Your services already collect database metrics via SQLAlchemy instrumentation:
**Metrics automatically collected:**
- `db.client.connections.usage` - Active database connections
- `db.client.operation.duration` - Query duration (SELECT, INSERT, UPDATE, DELETE)
- Query traces with SQL statements (in trace spans)
**View in SigNoz:**
1. Go to Traces → Select a service → Filter by `db.operation`
2. See individual database queries with duration
3. Identify slow queries causing latency
### PostgreSQL Metrics Reference
| Metric | Description |
|--------|-------------|
| `postgresql.backends` | Number of active connections |
| `postgresql.database.size` | Database size in bytes |
| `postgresql.commits` | Transaction commits |
| `postgresql.rollbacks` | Transaction rollbacks |
| `postgresql.deadlocks` | Deadlock count |
| `postgresql.blocks_read` | Blocks read from disk |
| `postgresql.table.size` | Table size in bytes |
| `postgresql.index.size` | Index size in bytes |
| `postgresql.rows` | Rows inserted/updated/deleted |
## Redis Monitoring
### Option 1: OpenTelemetry Collector with Redis Receiver (Recommended)
```yaml
# Add to postgres-otel-collector config or create separate collector
receivers:
redis:
endpoint: redis-service.bakery-ia:6379
password: ${REDIS_PASSWORD}
collection_interval: 30s
tls:
insecure_skip_verify: false
cert_file: /etc/redis-tls/redis-cert.pem
key_file: /etc/redis-tls/redis-key.pem
ca_file: /etc/redis-tls/ca-cert.pem
metrics:
redis.clients.connected: true
redis.clients.blocked: true
redis.commands.processed: true
redis.commands.duration: true
redis.db.keys: true
redis.db.expires: true
redis.keyspace.hits: true
redis.keyspace.misses: true
redis.memory.used: true
redis.memory.peak: true
redis.memory.fragmentation_ratio: true
redis.cpu.time: true
redis.replication.offset: true
```
### Option 2: Application-Level Redis Metrics (Already Implemented)
Your services already collect Redis metrics via Redis instrumentation:
**Metrics automatically collected:**
- Redis command traces (GET, SET, etc.) in spans
- Command duration
- Command errors
### Redis Metrics Reference
| Metric | Description |
|--------|-------------|
| `redis.clients.connected` | Connected clients |
| `redis.commands.processed` | Total commands processed |
| `redis.keyspace.hits` | Cache hit rate |
| `redis.keyspace.misses` | Cache miss rate |
| `redis.memory.used` | Memory usage in bytes |
| `redis.memory.fragmentation_ratio` | Memory fragmentation |
| `redis.db.keys` | Number of keys per database |
## RabbitMQ Monitoring
### Option 1: RabbitMQ Management Plugin + OpenTelemetry (Recommended)
RabbitMQ exposes metrics via its management API.
```yaml
receivers:
rabbitmq:
endpoint: http://rabbitmq-service.bakery-ia:15672
username: ${RABBITMQ_USER}
password: ${RABBITMQ_PASSWORD}
collection_interval: 30s
metrics:
rabbitmq.consumer.count: true
rabbitmq.message.current: true
rabbitmq.message.acknowledged: true
rabbitmq.message.delivered: true
rabbitmq.message.published: true
rabbitmq.queue.count: true
```
### RabbitMQ Metrics Reference
| Metric | Description |
|--------|-------------|
| `rabbitmq.consumer.count` | Active consumers |
| `rabbitmq.message.current` | Messages in queue |
| `rabbitmq.message.acknowledged` | Messages acknowledged |
| `rabbitmq.message.delivered` | Messages delivered |
| `rabbitmq.message.published` | Messages published |
| `rabbitmq.queue.count` | Number of queues |
## Database Logs Export
### PostgreSQL Logs
#### Option 1: Configure PostgreSQL to Log to Stdout (Kubernetes-native)
PostgreSQL logs should go to stdout/stderr, which Kubernetes automatically captures.
**Update PostgreSQL configuration:**
```yaml
# In your postgres deployment ConfigMap
apiVersion: v1
kind: ConfigMap
metadata:
name: postgres-config
namespace: bakery-ia
data:
postgresql.conf: |
# Logging
logging_collector = off # Use stdout/stderr instead
log_destination = 'stderr'
log_statement = 'all' # Or 'ddl', 'mod', 'none'
log_duration = on
log_line_prefix = '%t [%p]: user=%u,db=%d,app=%a,client=%h '
log_min_duration_statement = 100 # Log queries > 100ms
log_checkpoints = on
log_connections = on
log_disconnections = on
log_lock_waits = on
```
#### Option 2: OpenTelemetry Filelog Receiver
If PostgreSQL writes to files, use filelog receiver:
```yaml
receivers:
filelog/postgres:
include:
- /var/log/postgresql/*.log
start_at: end
operators:
- type: regex_parser
regex: '^(?P<timestamp>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}.\d+) \[(?P<pid>\d+)\]: user=(?P<user>[^,]+),db=(?P<database>[^,]+),app=(?P<application>[^,]+),client=(?P<client>[^ ]+) (?P<level>[A-Z]+): (?P<message>.*)'
timestamp:
parse_from: attributes.timestamp
layout: '%Y-%m-%d %H:%M:%S.%f'
- type: move
from: attributes.level
to: severity
- type: add
field: attributes["database.system"]
value: "postgresql"
processors:
resource/postgres:
attributes:
- key: database.system
value: postgresql
action: insert
- key: service.name
value: postgres-logs
action: insert
exporters:
otlphttp/logs:
endpoint: http://signoz-otel-collector.signoz.svc.cluster.local:4318/v1/logs
service:
pipelines:
logs/postgres:
receivers: [filelog/postgres]
processors: [resource/postgres, batch]
exporters: [otlphttp/logs]
```
### Redis Logs
Redis logs should go to stdout, which Kubernetes captures automatically. View them in SigNoz by:
1. Ensuring Redis pods log to stdout
2. No additional configuration needed - Kubernetes logs are available
3. Optional: Use Kubernetes logs collection (see below)
### Kubernetes Logs Collection (All Pods)
Deploy a DaemonSet to collect all Kubernetes pod logs:
```yaml
# infrastructure/kubernetes/base/monitoring/logs-collector-daemonset.yaml
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: otel-logs-collector
namespace: bakery-ia
spec:
selector:

## Dashboard Examples
### PostgreSQL Dashboard in SigNoz
Create a custom dashboard with these panels:
1. **Active Connections**
- Query: `postgresql.backends`
- Group by: `database.name`
2. **Query Rate**
- Query: `rate(postgresql.commits[5m])`
3. **Database Size**
- Query: `postgresql.database.size`
- Group by: `database.name`
4. **Slow Queries**
- Go to Traces
- Filter: `db.system="postgresql" AND duration > 1s`
- See slow queries with full SQL
5. **Connection Pool Usage**
- Query: `db.client.connections.usage`
- Group by: `service`
### Redis Dashboard
1. **Hit Rate**
- Query: `redis.keyspace.hits / (redis.keyspace.hits + redis.keyspace.misses)`
2. **Memory Usage**
- Query: `redis.memory.used`
3. **Connected Clients**
- Query: `redis.clients.connected`
4. **Commands Per Second**
- Query: `rate(redis.commands.processed[1m])`
## Quick Reference: What's Monitored
| Database | Metrics | Logs | Traces |
|----------|---------|------|--------|
| **PostgreSQL** | ✅ Via receiver<br>✅ Via app instrumentation | ✅ Stdout/stderr<br>✅ Optional filelog | ✅ Query spans in traces |
| **Redis** | ✅ Via receiver<br>✅ Via app instrumentation | ✅ Stdout/stderr | ✅ Command spans in traces |
| **RabbitMQ** | ✅ Via receiver | ✅ Stdout/stderr | ✅ Publish/consume spans |
## Deployment Checklist
- [ ] Deploy OpenTelemetry collector for database metrics
- [ ] Create monitoring users in PostgreSQL
- [ ] Configure database logging to stdout
- [ ] Verify metrics appear in SigNoz
- [ ] Create database dashboards
- [ ] Set up alerts for connection limits, slow queries, high memory
## Troubleshooting
### No PostgreSQL metrics
```bash
# Check collector logs
kubectl logs -n bakery-ia deployment/postgres-otel-collector
# Test connection to database
kubectl exec -n bakery-ia deployment/postgres-otel-collector -- \
psql -h auth-db-service -U otel_monitor -d auth_db -c "SELECT 1"
```
### No Redis metrics
```bash
# Check Redis connection
kubectl exec -n bakery-ia deployment/postgres-otel-collector -- \
redis-cli -h redis-service -a PASSWORD ping
```
### Logs not appearing
```bash
# Check if logs are going to stdout
kubectl logs -n bakery-ia postgres-pod-name
# Check logs collector
kubectl logs -n bakery-ia daemonset/otel-logs-collector
```
## Best Practices
1. **Use dedicated monitoring users** - Don't use application database users
2. **Set appropriate collection intervals** - 30s-60s for metrics
3. **Monitor connection pool saturation** - Alert before exhausting connections

# Docker Hub Configuration Guide
This guide explains how to configure Docker Hub for all image pulls in the Bakery IA project.
## Overview
The project has been configured to use Docker Hub credentials for pulling both:
- **Base images** (postgres, redis, python, node, nginx, etc.)
- **Custom bakery images** (bakery/auth-service, bakery/gateway, etc.)
## Quick Start
### 1. Create Docker Hub Secret in Kubernetes
Run the automated setup script:
```bash
./infrastructure/kubernetes/setup-dockerhub-secrets.sh
```
This script will:
- Create the `dockerhub-creds` secret in all namespaces (bakery-ia, bakery-ia-dev, bakery-ia-prod, default)
- Use the credentials: `uals` / `dckr_pat_zzEY5Q58x1S0puraIoKEtbpue3A`
### 2. Apply Updated Kubernetes Manifests
All manifests have been updated with `imagePullSecrets`. Apply them:
```bash
# For development
kubectl apply -k infrastructure/kubernetes/overlays/dev
# For production
kubectl apply -k infrastructure/kubernetes/overlays/prod
```
### 3. Verify Pods Can Pull Images
```bash
# Check pod status
kubectl get pods -n bakery-ia
# Check events for image pull status
kubectl get events -n bakery-ia --sort-by='.lastTimestamp'
# Describe a specific pod to see image pull details
kubectl describe pod <pod-name> -n bakery-ia
```
## Manual Setup
If you prefer to create the secret manually:
```bash
kubectl create secret docker-registry dockerhub-creds \
--docker-server=docker.io \
--docker-username=uals \
--docker-password=dckr_pat_zzEY5Q58x1S0puraIoKEtbpue3A \
--docker-email=ualfaro@gmail.com \
-n bakery-ia
```
Repeat for other namespaces:
```bash
kubectl create secret docker-registry dockerhub-creds \
--docker-server=docker.io \
--docker-username=uals \
--docker-password=dckr_pat_zzEY5Q58x1S0puraIoKEtbpue3A \
--docker-email=ualfaro@gmail.com \
-n bakery-ia-dev
kubectl create secret docker-registry dockerhub-creds \
--docker-server=docker.io \
--docker-username=uals \
--docker-password=dckr_pat_zzEY5Q58x1S0puraIoKEtbpue3A \
--docker-email=ualfaro@gmail.com \
-n bakery-ia-prod
```
## What Was Changed
### 1. Kubernetes Manifests (47 files updated)
All deployments, jobs, and cronjobs now include `imagePullSecrets`:
```yaml
spec:
template:
spec:
imagePullSecrets:
- name: dockerhub-creds
containers:
- name: ...
```
**Files Updated:**
- **19 Service Deployments**: All microservices (auth, tenant, forecasting, etc.)
- **21 Database Deployments**: All PostgreSQL instances, Redis, RabbitMQ
- **21 Migration Jobs**: All database migration jobs
- **2 CronJobs**: demo-cleanup, external-data-rotation
- **2 Standalone Jobs**: external-data-init, nominatim-init
- **1 Worker Deployment**: demo-cleanup-worker
### 2. Tiltfile Configuration
The Tiltfile now supports both local registry and Docker Hub:
**Default (Local Registry):**
```bash
tilt up
```
**Docker Hub Mode:**
```bash
export USE_DOCKERHUB=true
export DOCKERHUB_USERNAME=uals
tilt up
```
### 3. Scripts
Two new scripts were created:
1. **[setup-dockerhub-secrets.sh](../infrastructure/kubernetes/setup-dockerhub-secrets.sh)**
- Creates Docker Hub secrets in all namespaces
- Idempotent (safe to run multiple times)
2. **[add-image-pull-secrets.sh](../infrastructure/kubernetes/add-image-pull-secrets.sh)**
- Adds `imagePullSecrets` to all Kubernetes manifests
- Already run (no need to run again unless adding new manifests)
## Using Docker Hub with Tilt
To use Docker Hub for development with Tilt:
```bash
# Login to Docker Hub first
docker login -u uals
# Enable Docker Hub mode
export USE_DOCKERHUB=true
export DOCKERHUB_USERNAME=uals
# Start Tilt
tilt up
```
This will:
- Build images locally
- Tag them as `docker.io/uals/<image-name>`
- Push them to Docker Hub
- Deploy to Kubernetes with imagePullSecrets
## Images Configuration
### Base Images (from Docker Hub)
These images are pulled from Docker Hub's public registry:
- `python:3.11-slim` - Python base for all microservices
- `node:18-alpine` - Node.js for frontend builder
- `nginx:1.25-alpine` - Nginx for frontend production
- `postgres:17-alpine` - PostgreSQL databases
- `redis:7.4-alpine` - Redis cache
- `rabbitmq:4.1-management-alpine` - RabbitMQ message broker
- `busybox:latest` - Utility container
- `curlimages/curl:latest` - Curl utility
- `mediagis/nominatim:4.4` - Geolocation service
### Custom Images (bakery/*)
These images are built by the project:
**Infrastructure:**
- `bakery/gateway`
- `bakery/dashboard`
**Core Services:**
- `bakery/auth-service`
- `bakery/tenant-service`
**Data & Analytics:**
- `bakery/training-service`
- `bakery/forecasting-service`
- `bakery/ai-insights-service`
**Operations:**
- `bakery/sales-service`
- `bakery/inventory-service`
- `bakery/production-service`
- `bakery/procurement-service`
- `bakery/distribution-service`
**Supporting:**
- `bakery/recipes-service`
- `bakery/suppliers-service`
- `bakery/pos-service`
- `bakery/orders-service`
- `bakery/external-service`
**Platform:**
- `bakery/notification-service`
- `bakery/alert-processor`
- `bakery/orchestrator-service`
**Demo:**
- `bakery/demo-session-service`
## Pushing Custom Images to Docker Hub
Use the existing tag-and-push script:
```bash
# Login first
docker login -u uals
# Tag and push all images
./scripts/tag-and-push-images.sh
```
Or manually for a specific image:
```bash
# Build
docker build -t bakery/auth-service:latest -f services/auth/Dockerfile .
# Tag for Docker Hub
docker tag bakery/auth-service:latest uals/bakery-auth-service:latest
# Push
docker push uals/bakery-auth-service:latest
```
## Troubleshooting
### Problem: ImagePullBackOff error
Check if the secret exists:
```bash
kubectl get secret dockerhub-creds -n bakery-ia
```
Verify secret is correctly configured:
```bash
kubectl get secret dockerhub-creds -n bakery-ia -o yaml
```
Check pod events:
```bash
kubectl describe pod <pod-name> -n bakery-ia
```
### Problem: Authentication failure
The Docker Hub credentials might be incorrect or expired. Update the secret:
```bash
# Delete old secret
kubectl delete secret dockerhub-creds -n bakery-ia
# Create new secret with updated credentials
kubectl create secret docker-registry dockerhub-creds \
--docker-server=docker.io \
--docker-username=<your-username> \
--docker-password=<your-token> \
--docker-email=<your-email> \
-n bakery-ia
```
### Problem: Pod still using old credentials
Restart the pod to pick up the new secret:
```bash
kubectl rollout restart deployment/<deployment-name> -n bakery-ia
```
## Security Best Practices
1. **Use Docker Hub Access Tokens** (not passwords)
- Create at: https://hub.docker.com/settings/security
- Set appropriate permissions (Read-only for pulls)
2. **Rotate Credentials Regularly**
- Update the secret every 90 days
- Use the setup script for consistent updates
3. **Limit Secret Access**
- Only grant access to necessary namespaces
- Use RBAC to control who can read secrets
4. **Monitor Usage**
- Check Docker Hub pull rate limits
- Monitor for unauthorized access
## Rate Limits
Docker Hub has rate limits for image pulls:
- **Anonymous users**: 100 pulls per 6 hours per IP
- **Authenticated users**: 200 pulls per 6 hours
- **Pro/Team**: Unlimited
Using authentication (imagePullSecrets) ensures you get the authenticated user rate limit.
## Environment Variables
For CI/CD or automated deployments, use these environment variables:
```bash
export DOCKER_USERNAME=uals
export DOCKER_PASSWORD=dckr_pat_zzEY5Q58x1S0puraIoKEtbpue3A
export DOCKER_EMAIL=ualfaro@gmail.com
```
## Next Steps
1. ✅ Docker Hub secret created in all namespaces
2. ✅ All Kubernetes manifests updated with imagePullSecrets
3. ✅ Tiltfile configured for optional Docker Hub usage
4. 🔄 Apply manifests to your cluster
5. 🔄 Verify pods can pull images successfully

2. Verify Docker Hub credentials at: https://hub.docker.com/settings/security
3. Check Kubernetes events: `kubectl get events -A --sort-by='.lastTimestamp'`
4. Review pod logs: `kubectl logs -n bakery-ia <pod-name>`

# - System metrics (if ENABLE_SYSTEM_METRICS=true)
# - Logs (if OTEL_LOGS_EXPORTER=otlp)
```
## 🎨 Dashboard Examples
### Service Health Dashboard
Create a dashboard with:
1. **Request Rate** - `rate(http_requests_total[5m])`
2. **Error Rate** - `rate(http_requests_total{status_code=~"5.."}[5m])`
3. **Latency (P95)** - `histogram_quantile(0.95, http_request_duration_seconds)`
4. **Active Requests** - `active_requests`
5. **CPU Usage** - `process.cpu.utilization`
6. **Memory Usage** - `process.memory.utilization`
### Database Dashboard
1. **PostgreSQL Connections** - `postgresql.backends`
2. **Database Size** - `postgresql.database.size`
3. **Transaction Rate** - `rate(postgresql.commits[5m])`
4. **Redis Hit Rate** - `redis.keyspace.hits / (redis.keyspace.hits + redis.keyspace.misses)`
5. **RabbitMQ Queue Depth** - `rabbitmq.message.current`
## ⚠️ Alerts
### Recommended Alerts
**Application:**
- High error rate (>5% of requests failing)
- High latency (P95 > 1s)
- Service down (no metrics for 5 minutes)
**System:**
- High CPU (>80% for 5 minutes)
- High memory (>90%)
- Disk space low (<10%)
**Database:**
- PostgreSQL connections near max (>80% of max_connections)
- Slow queries (>5s)
- Redis memory high (>80%)
- RabbitMQ queue buildup (>10k messages)
## 🐛 Troubleshooting
### No Data in SigNoz
```bash
# 1. Check service logs
kubectl logs -n bakery-ia deployment/auth-service | grep -i otel
# 2. Check SigNoz collector
kubectl logs -n signoz deployment/signoz-otel-collector
# 3. Test connectivity
kubectl exec -n bakery-ia deployment/auth-service -- \
curl -v http://signoz-otel-collector.signoz.svc.cluster.local:4318
```
### Database Metrics Missing
```bash
# Check database monitoring collector
kubectl logs -n bakery-ia deployment/database-otel-collector
# Verify monitoring user exists
kubectl exec -n bakery-ia deployment/auth-db -- \
psql -U postgres -c "\du otel_monitor"
```
### Traces Not Correlated with Logs
Ensure `OTEL_LOGS_EXPORTER=otlp` is set in service environment variables.
## 🎯 Best Practices
1. **Always use structured logging** - Add context with key-value pairs
2. **Add custom spans** - For important business operations
3. **Set appropriate log levels** - INFO for production, DEBUG for dev
4. **Monitor your monitors** - Alert on collector failures
5. **Regular retention policy reviews** - Balance cost vs. data retention
6. **Create service dashboards** - One dashboard per service
7. **Set up critical alerts first** - Service down, high error rate
8. **Document custom metrics** - Explain business-specific metrics
## 📊 Performance Impact
**Resource Usage (per service):**
- CPU: +5-10% (instrumentation overhead)
- Memory: +50-100MB (SDK and buffers)
- Network: Minimal (batched export every 60s)
**Latency Impact:**
- Per request: <1ms (async instrumentation)
- No impact on user-facing latency
**Storage (SigNoz):**
- Traces: ~1GB per million requests
- Metrics: ~100MB per service per day
- Logs: Varies by log volume
## 🔐 Security Considerations
1. **Use dedicated monitoring users** - Never use app credentials
2. **Limit collector permissions** - Read-only access to databases
3. **Secure OTLP endpoints** - Use TLS in production
4. **Sanitize sensitive data** - Don't log passwords, tokens
5. **Network policies** - Restrict collector network access
6. **RBAC** - Limit SigNoz UI access per team
## 🚀 Next Steps
1. **Deploy to production** - Update production SigNoz config
2. **Create team dashboards** - Per-service and system-wide views
3. **Set up alerts** - Start with critical service health alerts
4. **Train team** - SigNoz UI usage, query language
5. **Document runbooks** - How to respond to alerts
6. **Optimize retention** - Based on actual data volume
7. **Add custom metrics** - Business-specific KPIs

# SigNoz Monitoring Quick Start
Get complete observability (metrics, logs, traces, system metrics) in under 10 minutes using OpenTelemetry.
## What You'll Get
✅ **Distributed Tracing** - Complete request flows across all services
✅ **Application Metrics** - HTTP requests, durations, error rates, custom business metrics
✅ **System Metrics** - CPU usage, memory usage, disk I/O, network I/O per service
✅ **Structured Logs** - Searchable logs correlated with traces
✅ **Unified Dashboard** - Single UI for all telemetry data
**All data pushed via OpenTelemetry OTLP protocol - No Prometheus, no scraping needed!**
## Prerequisites
- Kubernetes cluster running (Kind/Minikube/Production)
- Helm 3.x installed
- kubectl configured
## Step 1: Deploy SigNoz
```bash
# Add Helm repository
helm repo add signoz https://charts.signoz.io
helm repo update
# Create namespace
kubectl create namespace signoz
# Install SigNoz
helm install signoz signoz/signoz \
-n signoz \
-f infrastructure/helm/signoz-values-dev.yaml
# Wait for pods to be ready (2-3 minutes)
kubectl wait --for=condition=ready pod -l app=signoz -n signoz --timeout=300s
```
## Step 2: Configure Services
Each service needs OpenTelemetry environment variables. The auth-service is already configured as an example.
### Quick Configuration (for remaining services)
Add these environment variables to each service deployment:
```yaml
env:
# OpenTelemetry Collector endpoint
- name: OTEL_COLLECTOR_ENDPOINT
value: "http://signoz-otel-collector.signoz.svc.cluster.local:4318"
- name: OTEL_EXPORTER_OTLP_ENDPOINT
value: "http://signoz-otel-collector.signoz.svc.cluster.local:4318"
- name: OTEL_SERVICE_NAME
value: "your-service-name" # e.g., "inventory-service"
# Enable tracing
- name: ENABLE_TRACING
value: "true"
# Enable logs export
- name: OTEL_LOGS_EXPORTER
value: "otlp"
# Enable metrics export (includes system metrics)
- name: ENABLE_OTEL_METRICS
value: "true"
- name: ENABLE_SYSTEM_METRICS
value: "true"
```
### Using the Configuration Script
```bash
# Generate configuration patches for all services
./infrastructure/kubernetes/add-monitoring-config.sh
# This creates /tmp/*-otel-patch.yaml files
# Review and manually add to each service deployment
```
## Step 3: Deploy Updated Services
```bash
# Apply updated configurations
kubectl apply -k infrastructure/kubernetes/overlays/dev/
# Or restart services to pick up new env vars
kubectl rollout restart deployment -n bakery-ia
# Wait for rollout
kubectl rollout status deployment -n bakery-ia --timeout=5m
```
## Step 4: Access SigNoz UI
### Via Ingress
```bash
# Add to /etc/hosts if needed
echo "127.0.0.1 monitoring.bakery-ia.local" | sudo tee -a /etc/hosts
# Access UI
open https://monitoring.bakery-ia.local
```
### Via Port Forward
```bash
kubectl port-forward -n signoz svc/signoz-frontend 3301:3301
open http://localhost:3301
```

- User registrations
- Orders created
- Login attempts
- etc.
### Logs
1. Go to **Logs** tab
2. Filter by service: `service_name="auth-service"`
3. Search for specific messages
4. See structured fields (user_id, tenant_id, etc.)
### Trace-Log Correlation
1. Find a trace in **Traces** tab
2. Note the `trace_id`
3. Go to **Logs** tab
4. Filter: `trace_id="<the-trace-id>"`
5. See all logs for that specific request!
## Verification Commands
```bash
# Check if services are sending telemetry
kubectl logs -n bakery-ia deployment/auth-service | grep -i "telemetry\|otel"
# Check SigNoz collector is receiving data
kubectl logs -n signoz deployment/signoz-otel-collector | tail -50
# Test connectivity to collector
kubectl exec -n bakery-ia deployment/auth-service -- \
curl -v http://signoz-otel-collector.signoz.svc.cluster.local:4318
```
## Common Issues
### No data in SigNoz
```bash
# 1. Verify environment variables are set
kubectl get deployment auth-service -n bakery-ia -o yaml | grep OTEL
# 2. Check collector logs
kubectl logs -n signoz deployment/signoz-otel-collector
# 3. Restart service
kubectl rollout restart deployment/auth-service -n bakery-ia
```
### Services not appearing
```bash
# Check network connectivity
kubectl exec -n bakery-ia deployment/auth-service -- \
curl http://signoz-otel-collector.signoz.svc.cluster.local:4318
# Should return: connection successful (not connection refused)
```

## What Makes This Different
**Pure OpenTelemetry** - No Prometheus involved:
- ✅ All metrics pushed via OTLP (not scraped)
- ✅ Automatic system metrics collection (CPU, memory, disk, network)
- ✅ Unified data model for all telemetry
- ✅ Native trace-metric-log correlation
- ✅ Lower resource usage (no scraping overhead)
## Next Steps
- **Create Dashboards** - Build custom views for your metrics
- **Set Up Alerts** - Configure alerts for errors, latency, resource usage
- **Explore System Metrics** - Monitor CPU, memory per service
- **Query Logs** - Use powerful log query language
- **Correlate Everything** - Jump from traces → logs → metrics

```
### Key Components
1. **Services**: Generate telemetry data using OpenTelemetry SDK
2. **OpenTelemetry Collector**: Receives, processes, and exports telemetry
3. **ClickHouse**: Stores traces, metrics, and logs
4. **SigNoz UI**: Query and visualize all telemetry data
## Prerequisites
- Kubernetes cluster (Kind, Minikube, or production cluster)
- Helm 3.x installed
- kubectl configured
- At least 4GB RAM available for SigNoz components
## SigNoz Deployment
### 1. Add SigNoz Helm Repository
```bash
helm repo add signoz https://charts.signoz.io
helm repo update
```
### 2. Create Namespace
```bash
kubectl create namespace signoz
```
### 3. Deploy SigNoz
```bash
# For development environment
helm install signoz signoz/signoz \
-n signoz \
-f infrastructure/helm/signoz-values-dev.yaml
# For production environment
helm install signoz signoz/signoz \
-n signoz \
-f infrastructure/helm/signoz-values-prod.yaml
```
### 4. Verify Deployment
```bash
# Check all pods are running
kubectl get pods -n signoz
# Expected output:
# signoz-alertmanager-0
# signoz-clickhouse-0
# signoz-frontend-*
# signoz-otel-collector-*
# signoz-query-service-*
# Check services
kubectl get svc -n signoz
```
## Service Configuration
Each microservice needs to be configured to send telemetry to SigNoz.
### Environment Variables
Add these environment variables to your service deployments:
```yaml
env:
# OpenTelemetry Collector endpoint
- name: OTEL_COLLECTOR_ENDPOINT
value: "http://signoz-otel-collector.signoz.svc.cluster.local:4318"
- name: OTEL_EXPORTER_OTLP_ENDPOINT
value: "http://signoz-otel-collector.signoz.svc.cluster.local:4318"
# Service identification
- name: OTEL_SERVICE_NAME
value: "your-service-name" # e.g., "auth-service"
# Enable tracing
- name: ENABLE_TRACING
value: "true"
# Enable logs export
- name: OTEL_LOGS_EXPORTER
value: "otlp"
- name: OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED
value: "true"
# Enable metrics export (optional, default: true)
- name: ENABLE_OTEL_METRICS
value: "true"
```
### Prometheus Annotations
Add these annotations to enable Prometheus metrics scraping:
```yaml
metadata:
annotations:
prometheus.io/scrape: "true"
prometheus.io/port: "8000"
prometheus.io/path: "/metrics"
```
### Complete Example
See [infrastructure/kubernetes/base/components/auth/auth-service.yaml](../infrastructure/kubernetes/base/components/auth/auth-service.yaml) for a complete example.
### Automated Configuration Script
Use the provided script to add monitoring configuration to all services:
```bash
# Run from project root
./infrastructure/kubernetes/add-monitoring-config.sh
```
## Data Flow
### 1. Traces
**Automatic Instrumentation:**
```python
# In your service's main.py
from shared.service_base import StandardFastAPIService
service = AuthService() # Extends StandardFastAPIService
app = service.create_app()
# Tracing is automatically enabled if ENABLE_TRACING=true
# All FastAPI endpoints, HTTP clients, Redis, PostgreSQL are auto-instrumented
```
**Manual Instrumentation:**
```python
from shared.monitoring.tracing import add_trace_attributes, add_trace_event
# Add custom attributes to current span
add_trace_attributes(
user_id="123",
tenant_id="abc",
operation="user_registration"
)
# Add events for important operations
add_trace_event("user_authenticated", user_id="123", method="jwt")
```
### 2. Metrics
**Dual Export Strategy:**
Services export metrics in two ways:
1. **Prometheus format** at `/metrics` endpoint (scraped by SigNoz)
2. **OTLP push** directly to SigNoz collector (real-time)
**Built-in Metrics:**
```python
# Automatically collected by BaseFastAPIService:
# - http_requests_total
# - http_request_duration_seconds
# - active_connections
```
**Custom Metrics:**
```python
# Define in your service
custom_metrics = {
"user_registrations": {
"type": "counter",
"description": "Total user registrations",
"labels": ["status"]
},
"login_duration_seconds": {
"type": "histogram",
"description": "Login request duration"
}
}
service = AuthService(custom_metrics=custom_metrics)
# Use in your code
service.metrics_collector.increment_counter(
"user_registrations",
labels={"status": "success"}
)
```
### 3. Logs
**Automatic Export:**
```python
# Logs are automatically exported if OTEL_LOGS_EXPORTER=otlp
import logging
logger = logging.getLogger(__name__)
# This will appear in SigNoz
logger.info("User logged in", extra={"user_id": "123", "tenant_id": "abc"})
```
**Structured Logging with Context:**
```python
from shared.monitoring.logs_exporter import add_log_context
# Add context that persists across log calls
log_ctx = add_log_context(
request_id="req_123",
user_id="user_456",
tenant_id="tenant_789"
)
# All subsequent logs include this context
log_ctx.info("Processing order") # Includes request_id, user_id, tenant_id
```
**Trace Correlation:**
```python
from shared.monitoring.logs_exporter import get_current_trace_context
# Get trace context for correlation
trace_ctx = get_current_trace_context()
logger.info("Processing request", extra=trace_ctx)
# Logs now include trace_id and span_id for correlation
```
## Verification
### 1. Check Service Health
```bash
# Check that services are exporting telemetry
kubectl logs -n bakery-ia deployment/auth-service | grep -i "telemetry\|otel\|signoz"
# Expected output includes:
# - "Distributed tracing configured"
# - "OpenTelemetry logs export configured"
# - "OpenTelemetry metrics export configured"
```
### 2. Access SigNoz UI
```bash
# Port-forward (for local development)
kubectl port-forward -n signoz svc/signoz-frontend 3301:3301
# Or via Ingress
open https://monitoring.bakery-ia.local
```
### 3. Verify Data Ingestion
**Traces:**
1. Go to SigNoz UI → Traces
2. You should see traces from your services
3. Click on a trace to see the full span tree
**Metrics:**
1. Go to SigNoz UI → Metrics
2. Query: `http_requests_total`
3. Filter by service: `service="auth-service"`
**Logs:**
1. Go to SigNoz UI → Logs
2. Filter by service: `service_name="auth-service"`
3. Search for specific log messages
### 4. Test Trace-Log Correlation
1. Find a trace in SigNoz UI
2. Copy the `trace_id`
3. Go to Logs tab
4. Search: `trace_id="<your-trace-id>"`
5. You should see all logs for that trace
## Troubleshooting
### No Data in SigNoz
**1. Check OpenTelemetry Collector:**
```bash
# Check collector logs
kubectl logs -n signoz deployment/signoz-otel-collector
# Should see:
# - "Receiver is starting"
# - "Exporter is starting"
# - No error messages
```
**2. Check Service Configuration:**
```bash
# Verify environment variables
kubectl get deployment auth-service -n bakery-ia -o yaml | grep -A 20 "env:"
# Verify annotations
kubectl get deployment auth-service -n bakery-ia -o yaml | grep -A 5 "annotations:"
```
**3. Check Network Connectivity:**
```bash
# Test from service pod
kubectl exec -n bakery-ia deployment/auth-service -- \
curl -v http://signoz-otel-collector.signoz.svc.cluster.local:4318/v1/traces
# Should return: 405 Method Not Allowed (POST required)
# If connection refused, check network policies
```
### Traces Not Appearing
**Check instrumentation:**
```python
# Verify tracing is enabled
import os
print(os.getenv("ENABLE_TRACING")) # Should be "true"
print(os.getenv("OTEL_COLLECTOR_ENDPOINT")) # Should be set
```
**Check trace sampling:**
```bash
# Verify sampling rate (default 100%)
kubectl logs -n bakery-ia deployment/auth-service | grep "sampling"
```
### Metrics Not Appearing
**1. Verify Prometheus annotations:**
```bash
kubectl get pods -n bakery-ia -o yaml | grep "prometheus.io"
```
**2. Test metrics endpoint:**
```bash
# Port-forward service
kubectl port-forward -n bakery-ia deployment/auth-service 8000:8000
# Test endpoint
curl http://localhost:8000/metrics
# Should return Prometheus format metrics
```
**3. Check SigNoz scrape configuration:**
```bash
# Check collector config
kubectl get configmap -n signoz signoz-otel-collector -o yaml | grep -A 30 "prometheus:"
```
### Logs Not Appearing
**1. Verify log export is enabled:**
```bash
kubectl get deployment auth-service -n bakery-ia -o yaml | grep OTEL_LOGS_EXPORTER
# Should return: OTEL_LOGS_EXPORTER=otlp
```
**2. Check log format:**
```bash
# Logs should be JSON formatted
kubectl logs -n bakery-ia deployment/auth-service | head -5
```
**3. Verify OTLP endpoint:**
```bash
# Test logs endpoint
kubectl exec -n bakery-ia deployment/auth-service -- \
curl -X POST http://signoz-otel-collector.signoz.svc.cluster.local:4318/v1/logs \
-H "Content-Type: application/json" \
-d '{"resourceLogs":[]}'
# Should return 200 OK or 400 Bad Request (not connection error)
```
## Performance Tuning
### For Development
The default configuration is optimized for local development with minimal resources.
### For Production
Update the following in `signoz-values-prod.yaml`:
```yaml
# Increase collector resources
otelCollector:
resources:
requests:
cpu: 500m
memory: 1Gi
limits:
cpu: 2000m
memory: 2Gi
# Increase batch sizes
config:
processors:
batch:
timeout: 10s
send_batch_size: 10000 # Increased from 1024
# Add more replicas
replicaCount: 2
```
## Best Practices
1. **Use Structured Logging**: Always use key-value pairs for better querying
2. **Add Context**: Include user_id, tenant_id, request_id in logs
3. **Trace Business Operations**: Add custom spans for important operations
4. **Monitor Collector Health**: Set up alerts for collector errors
5. **Retention Policy**: Configure ClickHouse retention based on needs

# Bakery IA - Production Monitoring Stack
This directory contains the complete production-ready monitoring infrastructure for the Bakery IA platform.
## 📊 Components
### Core Monitoring
- **Prometheus v3.0.1** - Time-series metrics database (2 replicas with HA)
- **Grafana v12.3.0** - Visualization and dashboarding
- **AlertManager v0.27.0** - Alert routing and notification (3 replicas with HA)
### Distributed Tracing
- **Jaeger v1.51** - Distributed tracing with persistent storage
### Exporters
- **PostgreSQL Exporter v0.15.0** - Database metrics and health
- **Node Exporter v1.7.0** - Infrastructure and OS-level metrics (DaemonSet)
## 🚀 Deployment
### Prerequisites
1. Kubernetes cluster (v1.24+)
2. kubectl configured
3. kustomize (v4.0+) or kubectl with kustomize support
4. Storage class available for PersistentVolumeClaims
### Production Deployment
```bash
# 1. Update secrets with production values
kubectl create secret generic grafana-admin \
--from-literal=admin-user=admin \
--from-literal=admin-password=$(openssl rand -base64 32) \
--namespace monitoring --dry-run=client -o yaml > secrets.yaml
# 2. Update AlertManager SMTP credentials
kubectl create secret generic alertmanager-secrets \
--from-literal=smtp-host="smtp.gmail.com:587" \
--from-literal=smtp-username="alerts@yourdomain.com" \
--from-literal=smtp-password="YOUR_SMTP_PASSWORD" \
--from-literal=smtp-from="alerts@yourdomain.com" \
--from-literal=slack-webhook-url="https://hooks.slack.com/services/YOUR/WEBHOOK/URL" \
--namespace monitoring --dry-run=client -o yaml >> secrets.yaml
# 3. Update PostgreSQL exporter connection string
kubectl create secret generic postgres-exporter \
--from-literal=data-source-name="postgresql://user:password@postgres.bakery-ia:5432/bakery?sslmode=require" \
--namespace monitoring --dry-run=client -o yaml >> secrets.yaml
# 4. Deploy monitoring stack
kubectl apply -k infrastructure/kubernetes/overlays/prod
# 5. Verify deployment
kubectl get pods -n monitoring
kubectl get pvc -n monitoring
```
### Local Development Deployment
For local Kind clusters, monitoring is disabled by default to save resources. To enable:
```bash
# Uncomment monitoring in overlays/dev/kustomization.yaml
# Then apply:
kubectl apply -k infrastructure/kubernetes/overlays/dev
```
## 🔐 Security Configuration
### Important Security Notes
⚠️ **NEVER commit real secrets to Git!**
The `secrets.yaml` file contains placeholder values. In production, use one of:
1. **Sealed Secrets** (Recommended)
```bash
kubectl apply -f https://github.com/bitnami-labs/sealed-secrets/releases/download/v0.24.0/controller.yaml
kubeseal --format=yaml < secrets.yaml > sealed-secrets.yaml
```
2. **External Secrets Operator**
```bash
helm install external-secrets external-secrets/external-secrets -n external-secrets
```
3. **Cloud Provider Secrets**
- AWS Secrets Manager
- GCP Secret Manager
- Azure Key Vault
### Grafana Admin Password
Change the default password immediately:
```bash
# Generate strong password
NEW_PASSWORD=$(openssl rand -base64 32)
# Update secret
kubectl patch secret grafana-admin -n monitoring \
-p="{\"data\":{\"admin-password\":\"$(echo -n $NEW_PASSWORD | base64)\"}}"
# Restart Grafana
kubectl rollout restart deployment grafana -n monitoring
```
## 📈 Accessing Monitoring Services
### Via Ingress (Production)
```
https://monitoring.yourdomain.com/grafana
https://monitoring.yourdomain.com/prometheus
https://monitoring.yourdomain.com/alertmanager
https://monitoring.yourdomain.com/jaeger
```
### Via Port Forwarding (Development)
```bash
# Grafana
kubectl port-forward -n monitoring svc/grafana 3000:3000
# Prometheus
kubectl port-forward -n monitoring svc/prometheus-external 9090:9090
# AlertManager
kubectl port-forward -n monitoring svc/alertmanager-external 9093:9093
# Jaeger
kubectl port-forward -n monitoring svc/jaeger-query 16686:16686
```
Then access:
- Grafana: http://localhost:3000
- Prometheus: http://localhost:9090
- AlertManager: http://localhost:9093
- Jaeger: http://localhost:16686
## 📊 Grafana Dashboards
### Pre-configured Dashboards
1. **Gateway Metrics** - API gateway performance
- Request rate by endpoint
- P95 latency
- Error rates
- Authentication metrics
2. **Services Overview** - Microservices health
- Request rate by service
- P99 latency
- Error rates by service
- Service health status
3. **Circuit Breakers** - Resilience patterns
- Circuit breaker states
- Trip rates
- Rejected requests
4. **PostgreSQL Monitoring** - Database health
- Connections, transactions, cache hit ratio
- Slow queries, locks, replication lag
5. **Node Metrics** - Infrastructure monitoring
- CPU, memory, disk, network per node
6. **AlertManager** - Alert management
- Active alerts, firing rate, notifications
7. **Business Metrics** - KPIs
- Service performance, tenant activity, ML metrics
### Creating Custom Dashboards
1. Login to Grafana (admin/[your-password])
2. Click "+ → Dashboard"
3. Add panels with Prometheus queries
4. Save dashboard
5. Export JSON and add to `grafana-dashboards.yaml`
## 🚨 Alert Configuration
### Alert Rules
Alert rules are defined in `alert-rules.yaml` and organized by category:
- **bakery_services** - Service health, errors, latency, memory
- **bakery_business** - Training jobs, ML accuracy, API limits
- **alert_system_health** - Alert system components, RabbitMQ, Redis
- **alert_system_performance** - Processing errors, delivery failures
- **alert_system_business** - Alert volume, response times
- **alert_system_capacity** - Queue sizes, storage performance
- **alert_system_critical** - System failures, data loss
- **monitoring_health** - Prometheus, AlertManager self-monitoring
### Alert Routing
Alerts are routed based on:
- **Severity** (critical, warning, info)
- **Component** (alert-system, database, infrastructure)
- **Service** name
### Notification Channels
Configure in `alertmanager.yaml`:
1. **Email** (default)
- critical-alerts@yourdomain.com
- oncall@yourdomain.com
2. **Slack** (optional, commented out)
- Update slack-webhook-url in secrets
- Uncomment slack_configs in alertmanager.yaml
3. **PagerDuty** (add if needed)
```yaml
pagerduty_configs:
- routing_key: YOUR_ROUTING_KEY
severity: '{{ .Labels.severity }}'
```
### Testing Alerts
```bash
# Fire a test alert
kubectl run test-alert --image=busybox -n bakery-ia --restart=Never -- sleep 3600
# Check alert in Prometheus
# Navigate to http://localhost:9090/alerts
# Check AlertManager
# Navigate to http://localhost:9093
```
## 🔍 Troubleshooting
### Prometheus Issues
```bash
# Check Prometheus logs
kubectl logs -n monitoring prometheus-0 -f
# Check Prometheus targets
kubectl port-forward -n monitoring svc/prometheus-external 9090:9090
# Visit http://localhost:9090/targets
# Check Prometheus configuration
kubectl get configmap prometheus-config -n monitoring -o yaml
```
### AlertManager Issues
```bash
# Check AlertManager logs
kubectl logs -n monitoring alertmanager-0 -f
# Check AlertManager configuration
kubectl exec -n monitoring alertmanager-0 -- cat /etc/alertmanager/alertmanager.yml
# Test SMTP connection
kubectl exec -n monitoring alertmanager-0 -- \
wget --spider --server-response --timeout=10 smtp://smtp.gmail.com:587
```
### Grafana Issues
```bash
# Check Grafana logs
kubectl logs -n monitoring deployment/grafana -f
# Reset Grafana admin password
kubectl exec -n monitoring deployment/grafana -- \
grafana-cli admin reset-admin-password NEW_PASSWORD
```
### PostgreSQL Exporter Issues
```bash
# Check exporter logs
kubectl logs -n monitoring deployment/postgres-exporter -f
# Test database connection
kubectl exec -n monitoring deployment/postgres-exporter -- \
wget -O- http://localhost:9187/metrics | grep pg_up
```
### Node Exporter Issues
```bash
# Check node exporter on specific node
kubectl logs -n monitoring daemonset/node-exporter --selector=kubernetes.io/hostname=NODE_NAME -f
# Check metrics endpoint
kubectl exec -n monitoring daemonset/node-exporter -- \
wget -O- http://localhost:9100/metrics | head -n 20
```
## 📏 Resource Requirements
### Minimum Requirements (Development)
- CPU: 2 cores
- Memory: 4Gi
- Storage: 30Gi
### Recommended Requirements (Production)
- CPU: 6-8 cores
- Memory: 16Gi
- Storage: 100Gi
### Component Resource Allocation
| Component | Replicas | CPU Request | Memory Request | CPU Limit | Memory Limit |
|-----------|----------|-------------|----------------|-----------|--------------|
| Prometheus | 2 | 500m | 1Gi | 1 | 2Gi |
| AlertManager | 3 | 100m | 128Mi | 500m | 256Mi |
| Grafana | 1 | 100m | 256Mi | 500m | 512Mi |
| Postgres Exporter | 1 | 50m | 64Mi | 200m | 128Mi |
| Node Exporter | 1/node | 50m | 64Mi | 200m | 128Mi |
| Jaeger | 1 | 250m | 512Mi | 500m | 1Gi |
## 🔄 High Availability
### Prometheus HA
- 2 replicas in StatefulSet
- Each has independent storage (volumeClaimTemplates)
- Anti-affinity to spread across nodes
- Both scrape the same targets independently
- Use Thanos for long-term storage and global query view (future enhancement)
### AlertManager HA
- 3 replicas in StatefulSet
- Clustered mode (gossip protocol)
- Automatic leader election
- Alert deduplication across instances
- Anti-affinity to spread across nodes
### PodDisruptionBudgets
Ensure minimum availability during:
- Node maintenance
- Cluster upgrades
- Rolling updates
```yaml
Prometheus: minAvailable=1 (out of 2)
AlertManager: minAvailable=2 (out of 3)
Grafana: minAvailable=1 (out of 1)
```
## 📊 Metrics Reference
### Application Metrics (from services)
```promql
# HTTP request rate
rate(http_requests_total[5m])
# HTTP error rate
rate(http_requests_total{status_code=~"5.."}[5m]) / rate(http_requests_total[5m])
# Request latency (P95)
histogram_quantile(0.95, rate(http_request_duration_seconds_bucket[5m]))
# Active connections
active_connections
```
### PostgreSQL Metrics
```promql
# Active connections
pg_stat_database_numbackends
# Transaction rate
rate(pg_stat_database_xact_commit[5m])
# Cache hit ratio
rate(pg_stat_database_blks_hit[5m]) /
(rate(pg_stat_database_blks_hit[5m]) + rate(pg_stat_database_blks_read[5m]))
# Replication lag
pg_replication_lag_seconds
```
### Node Metrics
```promql
# CPU usage
100 - (avg by (instance) (rate(node_cpu_seconds_total{mode="idle"}[5m])) * 100)
# Memory usage
(node_memory_MemTotal_bytes - node_memory_MemAvailable_bytes) / node_memory_MemTotal_bytes * 100
# Disk I/O
rate(node_disk_read_bytes_total[5m])
rate(node_disk_written_bytes_total[5m])
# Network traffic
rate(node_network_receive_bytes_total[5m])
rate(node_network_transmit_bytes_total[5m])
```
## 🔗 Distributed Tracing
### Jaeger Configuration
Services automatically send traces when `JAEGER_ENABLED=true`:
```yaml
# In prod-configmap.yaml
JAEGER_ENABLED: "true"
JAEGER_AGENT_HOST: "jaeger-agent.monitoring.svc.cluster.local"
JAEGER_AGENT_PORT: "6831"
```
### Viewing Traces
1. Access Jaeger UI: https://monitoring.yourdomain.com/jaeger
2. Select service from dropdown
3. Click "Find Traces"
4. Explore trace details, spans, and timing
### Trace Sampling
Current sampling: 100% (all traces collected)
For high-traffic production:
```yaml
# Adjust in shared/monitoring/tracing.py
JAEGER_SAMPLE_RATE: "0.1" # 10% of traces
```
