# 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:
|
||||

|
||||

|
||||
```
|
||||
|
||||
#### 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.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.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
|
||||
|
||||

|
||||
|
||||
## 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.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
|
||||

|
||||

## 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 |

|
||||
- [ ] 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
|
||||
4. **Track slow queries** - Set `log_min_duration_statement` appropriately
|
||||
5. **Monitor disk usage** - PostgreSQL database size growth
|
||||
6. **Track cache hit rates** - Redis keyspace hits/misses ratio

# 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

|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
### 1. Deploy SigNoz
|
||||
|
||||
```bash
|
||||
# Add Helm repository
|
||||
helm repo add signoz https://charts.signoz.io
|
||||
helm repo update
|
||||
|
||||
# Create namespace and install
|
||||
kubectl create namespace signoz
|
||||
helm install signoz signoz/signoz \
|
||||
-n signoz \
|
||||
-f infrastructure/helm/signoz-values-dev.yaml
|
||||
|
||||
# Wait for pods
|
||||
kubectl wait --for=condition=ready pod -l app=signoz -n signoz --timeout=300s
|
||||
```
|
||||
|
||||
### 2. Deploy Services with Monitoring
|
||||
|
||||
All services are already configured with OpenTelemetry environment variables.
|
||||
|
||||
```bash
|
||||
# Apply all services
|
||||
kubectl apply -k infrastructure/kubernetes/overlays/dev/
|
||||
|
||||
# Or restart existing services
|
||||
kubectl rollout restart deployment -n bakery-ia
|
||||
```
|
||||
|
||||
### 3. Deploy Database Monitoring
|
||||
|
||||
```bash
|
||||
# Run the setup script
|
||||
./infrastructure/kubernetes/setup-database-monitoring.sh
|
||||
|
||||
# This will:
|
||||
# - Create monitoring users in PostgreSQL
|
||||
# - Deploy OpenTelemetry collector for database metrics
|
||||
# - Start collecting PostgreSQL, Redis, RabbitMQ metrics
|
||||
```
|
||||
|
||||
### 4. Access SigNoz UI
|
||||
|
||||
```bash
|
||||
# Via ingress
|
||||
open https://monitoring.bakery-ia.local
|
||||
|
||||
# Or port-forward
|
||||
kubectl port-forward -n signoz svc/signoz-frontend 3301:3301
|
||||
open http://localhost:3301
|
||||
```

## 🎨 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

## 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
|
||||
```

|
||||
- 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 -- \
|
||||

## 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
|
