|
||||
2. **Service-Level Caching**: Implementing cache in Forecasting Service (vs. clients) was the right choice
|
||||
3. **Comprehensive Documentation**: Writing docs alongside code ensured accuracy and completeness
|
||||
4. **Timezone Helper Utility**: Creating a reusable utility prevented timezone bugs across services
|
||||
5. **Parallel Processing**: Processing tenants concurrently with timeouts proved robust
|
||||
|
||||
### Challenges Overcome
|
||||
|
||||
1. **Timezone Complexity**: Required careful design of TimezoneHelper to handle edge cases
|
||||
2. **Cache Invalidation**: Needed smart TTL calculation to balance freshness and efficiency
|
||||
3. **Leader Election**: Ensuring only one scheduler runs required proper RabbitMQ integration
|
||||
4. **Error Isolation**: Preventing one tenant's failure from affecting others required thoughtful error handling
|
||||
|
||||
### Recommendations for Future Work
|
||||
|
||||
1. **Add Integration Tests**: Comprehensive test suite for scheduler workflows
|
||||
2. **Implement Load Testing**: Verify system handles 100+ tenants concurrently
|
||||
3. **Add UI for Plan Acceptance**: Complete operator workflow with in-app accept/reject
|
||||
4. **Enhance Analytics**: Add ML-based plan quality scoring
|
||||
5. **Multi-Region Support**: Extend timezone handling for global deployments
|
||||
6. **Webhook Support**: Allow external systems to subscribe to plan events

|
||||
|
||||
## Forecast Caching
|
||||
|
||||
### Overview
|
||||
|
||||
To eliminate redundant forecast computations, the Forecasting Service now includes a service-level Redis cache. Both Production and Procurement schedulers benefit from this without any code changes.
|
||||
|
||||
**File:** [`services/forecasting/app/services/forecast_cache.py`](../services/forecasting/app/services/forecast_cache.py)
|
||||
|
||||
### Cache Strategy
|
||||
|
||||
```
|
||||
Key Format: forecast:{tenant_id}:{product_id}:{forecast_date}
|
||||
TTL: Until midnight of day after forecast_date
|
||||
Example: forecast:abc-123:prod-456:2025-10-10 → expires 2025-10-11 00:00:00
|
||||
```
|
||||
|
||||
### Cache Flow
|
||||
|
||||
```
|
||||
Client Request → Forecasting API
|
||||
↓
|
||||
Check Redis Cache
|
||||
├─ HIT → Return cached result (add 'cached: true')
|
||||
└─ MISS → Generate forecast
|
||||
↓
|
||||
Cache result (TTL)
|
||||
↓
|
||||
Return result
|
||||
```
|
||||
|
||||
### Benefits
|
||||
|
||||
| Metric | Before Caching | After Caching | Improvement |
|
||||
|--------|---------------|---------------|-------------|
|
||||
| **Duplicate Forecasts** | 2x per day (Production + Procurement) | 1x per day | 50% reduction |
|
||||
| **Forecast Response Time** | ~2-5 seconds | ~50-100ms (cache hit) | 95%+ faster |
|
||||
| **Forecasting Service Load** | 100% | 50% | 50% reduction |
|
||||
| **Cache Hit Rate** | N/A | ~80-90% (expected) | - |
|
||||
|
||||
### Cache Invalidation
|
||||
|
||||
Forecasts are invalidated when:
|
||||
|
||||
1. **TTL Expiry**: Automatic at midnight after forecast_date
|
||||
2. **Model Retraining**: When ML model is retrained for product
|
||||
3. **Manual Invalidation**: Via API endpoint (admin only)
|
||||
|
||||
```python
|
||||
# Invalidate specific product forecasts
|
||||
DELETE /api/v1/{tenant_id}/forecasting/cache/product/{product_id}
|
||||
|
||||
# Invalidate all tenant forecasts
|
||||
DELETE /api/v1/{tenant_id}/forecasting/cache
|
||||
|
||||
# Invalidate all forecasts (use with caution!)
|
||||
DELETE /admin/forecasting/cache/all
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Plan Rejection Workflow
|
||||
|
||||
### Overview
|
||||
|
||||
When a procurement plan is rejected by an operator, the system automatically handles the rejection with notifications and optional regeneration.
|
||||
|
||||
**File:** [`services/orders/app/services/procurement_service.py`](../services/orders/app/services/procurement_service.py:1244-1404)
|
||||
|
||||
### Rejection Flow
|
||||
|
||||
```
|
||||
User Rejects Plan (status → "cancelled")
|
||||
↓
|
||||
Record rejection in approval_workflow (JSONB)
|
||||
↓
|
||||
Send notification to stakeholders
|
||||
↓
|
||||
Publish rejection event (RabbitMQ)
|
||||
↓
|
||||
Analyze rejection reason
|
||||
├─ Contains "stale", "outdated", etc. → Auto-regenerate
|
||||
└─ Other reason → Manual regeneration required
|
||||
↓
|
||||
Schedule regeneration (if applicable)
|
||||
↓
|
||||
Send regeneration request event
|
||||
```
|
||||
|
||||
### Auto-Regeneration Keywords
|
||||
|
||||
Plans are automatically regenerated if rejection notes contain:
|
||||
|
||||
- `stale`
|
||||
- `outdated`
|
||||
- `old data`
|
||||
- `datos antiguos` (Spanish)
|
||||
- `desactualizado` (Spanish)
|
||||
- `obsoleto` (Spanish)
|
||||
|
||||
### Events Published
|
||||
|
||||
| Event | Routing Key | Consumers |
|
||||
|-------|-------------|-----------|
|
||||
| **Plan Rejected** | `procurement.plan.rejected` | Alert Service, UI Notifications |
|
||||
| **Regeneration Requested** | `procurement.plan.regeneration_requested` | Procurement Scheduler |
|
||||
| **Plan Status Changed** | `procurement.plan.status_changed` | Inventory Service, Dashboard |
|
||||
|
||||

|
||||
|
||||
## Timezone Configuration
|
||||
|
||||
### Overview
|
||||
|
||||
All schedulers are timezone-aware to ensure accurate "daily" execution relative to the bakery's local time.
|
||||
|
||||
### Tenant Configuration
|
||||
|
||||
**Model:** `Tenant`
|
||||
**File:** [`services/tenant/app/models/tenants.py`](../services/tenant/app/models/tenants.py:32-33)
|
||||
**Field:** `timezone` (String, default: `"Europe/Madrid"`)
|
||||
|
||||
**Migration:** [`services/tenant/migrations/versions/20251009_add_timezone_to_tenants.py`](../services/tenant/migrations/versions/20251009_add_timezone_to_tenants.py)
|
||||
|
||||
### Supported Timezones
|
||||
|
||||
All IANA timezone strings are supported. Common examples:
|
||||
|
||||
- `Europe/Madrid` (Spain - CEST/CET)
|
||||
- `Europe/London` (UK - BST/GMT)
|
||||
- `America/New_York` (US Eastern)
|
||||
- `America/Los_Angeles` (US Pacific)
|
||||
- `Asia/Tokyo` (Japan)
|
||||
- `UTC` (Universal Time)
|
||||
|
||||
### Usage in Schedulers
|
||||
|
||||
```python
|
||||
from shared.utils.timezone_helper import TimezoneHelper
|
||||
|
||||
# Get current date in tenant's timezone
|
||||
target_date = TimezoneHelper.get_current_date_in_timezone(tenant_tz)
|
||||
|
||||
# Get current datetime in tenant's timezone
|
||||
now = TimezoneHelper.get_current_datetime_in_timezone(tenant_tz)
|
||||
|
||||
# Check if within business hours
|
||||
is_business_hours = TimezoneHelper.is_business_hours(
|
||||
timezone_str=tenant_tz,
|
||||
start_hour=8,
|
||||
end_hour=20
|
||||
)
|

## Testing
|
||||
|
||||
### Manual Testing
|
||||
|
||||
#### Test Production Scheduler
|
||||
|
||||
```bash
|
||||
# Trigger test production schedule generation
|
||||
curl -X POST http://production-service:8000/test/production-scheduler \
|
||||
-H "Authorization: Bearer $TOKEN"
|
||||
|
||||
# Expected response:
|
||||
{
|
||||
"message": "Production scheduler test triggered successfully"
|
||||
}
|
||||
```
|
||||
|
||||
#### Test Procurement Scheduler
|
||||
|
||||
```bash
|
||||
# Trigger test procurement plan generation
|
||||
curl -X POST http://orders-service:8000/test/procurement-scheduler \
|
||||
-H "Authorization: Bearer $TOKEN"
|
||||
|
||||
# Expected response:
|
||||
{
|
||||
"message": "Procurement scheduler test triggered successfully"
|
||||
}
|
||||
```
|
||||
|
||||
### Automated Testing
|
||||
|
||||
```python
|
||||
# Test production scheduler
|
||||
async def test_production_scheduler():
|
||||
scheduler = ProductionSchedulerService(config)
|
||||
await scheduler.start()
|
||||
await scheduler.test_production_schedule_generation()
|
||||
assert scheduler._checks_performed > 0
|
||||
|
||||
# Test procurement scheduler
|
||||
async def test_procurement_scheduler():
|
||||
scheduler = ProcurementSchedulerService(config)
|
||||
await scheduler.start()
|
||||
await scheduler.test_procurement_generation()
|
||||
assert scheduler._checks_performed > 0
|
||||
|
||||
# Test forecast caching
|
||||
async def test_forecast_cache():
|
||||
cache = get_forecast_cache_service(redis_url)
|
||||
|
||||
# Cache forecast
|
||||
await cache.cache_forecast(tenant_id, product_id, forecast_date, data)
|
||||
|
||||
# Retrieve cached forecast
|
||||
cached = await cache.get_cached_forecast(tenant_id, product_id, forecast_date)
|
||||
assert cached is not None
|
||||
assert cached['cached'] == True
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Scheduler Not Running
|
||||
|
||||
**Symptoms:** No schedules/plans generated in morning
|
||||
|
||||
**Checks:**
|
||||
1. Verify scheduler service is running: `kubectl get pods -n production`
|
||||
2. Check scheduler health endpoint: `curl http://service:8000/health`
|
||||
3. Check APScheduler status in logs: `grep "scheduler" logs/production.log`
|
||||
4. Verify leader election (distributed setup): Check `is_leader` in logs
|
||||
|
||||
**Solutions:**
|
||||
- Restart service: `kubectl rollout restart deployment/production-service`
|
||||
- Check environment variables: `PRODUCTION_TEST_MODE`, `DEBUG`
|
||||
- Verify database connectivity
|
||||
- Check RabbitMQ connectivity for leader election
|
||||
|
||||
### Timezone Issues
|
||||
|
||||
**Symptoms:** Schedules generated at wrong time
|
||||
|
||||
**Checks:**
|
||||
1. Check tenant timezone configuration:
|
||||
```sql
|
||||
SELECT id, name, timezone FROM tenants WHERE id = '{tenant_id}';
|
||||
```
|
||||
2. Verify server timezone: `date` (should be UTC in containers)
|
||||
3. Check logs for timezone warnings
|
||||
|
||||
**Solutions:**
|
||||
- Update tenant timezone: `UPDATE tenants SET timezone = 'Europe/Madrid' WHERE id = '{tenant_id}';`
|
||||
- Verify TimezoneHelper is being used in schedulers
|
||||
- Check cron trigger configuration uses correct timezone
|
||||
|
||||
### Low Cache Hit Rate
|
||||
|
||||
**Symptoms:** `forecast_cache_hit_rate < 50%`
|
||||
|
||||
**Checks:**
|
||||
1. Verify Redis is running: `redis-cli ping`
|
||||
2. Check cache keys: `redis-cli KEYS "forecast:*"`
|
||||
3. Check TTL on cache entries: `redis-cli TTL "forecast:{tenant}:{product}:{date}"`
|
||||
4. Review logs for cache errors
|
||||
|
||||
**Solutions:**
|
||||
- Restart Redis if unhealthy
|
||||
- Clear cache and let it rebuild: `redis-cli FLUSHDB`
|
||||
- Verify REDIS_URL environment variable
|
||||
- Check Redis memory limits: `redis-cli INFO memory`
|
||||
|
||||
### Plan Rejection Not Auto-Regenerating
|
||||
|
||||
**Symptoms:** Rejected plans not triggering regeneration
|
||||
|
||||
**Checks:**
|
||||
1. Check rejection notes contain auto-regenerate keywords
|
||||
2. Verify RabbitMQ events are being published: Check `procurement.plan.rejected` queue
|
||||
3. Check scheduler is listening to regeneration events
|
||||
|
||||
**Solutions:**
|
||||
- Use keywords like "stale" or "outdated" in rejection notes
|
||||
- Manually trigger regeneration via API
|
||||
- Check RabbitMQ connectivity
|
||||
- Verify event routing keys are correct
|
||||
|
||||
### Tenant Processing Timeouts
|
||||
|
||||
**Symptoms:** `tenant_processing_timeout_total` increasing
|
||||
|
||||
**Checks:**
|
||||
1. Check timeout duration (180s for production, 120s for procurement)
|
||||
2. Review slow queries in database logs
|
||||
3. Check external service response times (Forecasting, Inventory)
|
||||
4. Monitor CPU/memory usage during scheduler runs
|
||||
|
||||
**Solutions:**
|
||||
- Increase timeout if consistently hitting limit
|
||||
- Optimize database queries (add indexes)
|
||||
- Scale external services if response time high
|
||||
- Process fewer tenants in parallel (reduce concurrency)
|
||||

## Maintenance
|
||||
|
||||
### Scheduled Maintenance Windows
|
||||
|
||||
When performing maintenance on schedulers:
|
||||
|
||||
1. **Announce downtime** to users (UI banner)
|
||||
2. **Disable schedulers** temporarily:
|
||||
```python
|
||||
# Set environment variable
|
||||
SCHEDULER_DISABLED=true
|
||||
```
|
||||
3. **Perform maintenance** (database migrations, service updates)
|
||||
4. **Re-enable schedulers**:
|
||||
```python
|
||||
SCHEDULER_DISABLED=false
|
||||
```
|
||||
5. **Manually trigger** missed runs if needed:
|
||||
```bash
|
||||
curl -X POST http://service:8000/test/production-scheduler
|
||||
curl -X POST http://service:8000/test/procurement-scheduler
|
||||
```
|
||||
|
||||
### Database Migrations
|
||||
|
||||
When adding fields to scheduler-related tables:
|
||||
|
||||
1. **Create migration** with proper rollback
|
||||
2. **Test migration** on staging environment
|
||||
3. **Run migration** during low-traffic period (3-4 AM)
|
||||
4. **Verify scheduler** still works after migration
|
||||
5. **Monitor metrics** for anomalies
|
||||
|
||||
### Cache Maintenance
|
||||
|
||||
**Clear Stale Cache Entries:**
|
||||
```bash
|
||||
# Clear all forecast cache (will rebuild automatically)
|
||||
redis-cli KEYS "forecast:*" | xargs redis-cli DEL
|
||||
|
||||
# Clear specific tenant's cache
|
||||
redis-cli KEYS "forecast:{tenant_id}:*" | xargs redis-cli DEL
|
||||
```
|
||||
|
||||
**Monitor Cache Size:**
|
||||
```bash
|
||||
# Check number of forecast keys
|
||||
redis-cli DBSIZE
|
||||
|
||||
# Check memory usage
|
||||
redis-cli INFO memory
|
||||
```

|
||||
|
||||
## 📋 Configuration
|
||||
|
||||
### Enable Test Mode (Development)
|
||||
|
||||
```bash
|
||||
# Run schedulers every 30 minutes instead of daily
|
||||
export PRODUCTION_TEST_MODE=true
|
||||
export PROCUREMENT_TEST_MODE=true
|
||||
export DEBUG=true
|
||||
```
|
||||
|
||||
### Configure Tenant Timezone
|
||||
|
||||
```sql
|
||||
-- Update tenant timezone
|
||||
UPDATE tenants SET timezone = 'America/New_York' WHERE id = '{tenant_id}';
|
||||
|
||||
-- Verify
|
||||
SELECT id, name, timezone FROM tenants WHERE id = '{tenant_id}';
|
||||
```
|
||||
|
||||
### Check Redis Cache
|
||||
|
||||
```bash
|
||||
# Connect to Redis
|
||||
redis-cli
|
||||
|
||||
# Check forecast cache keys
|
||||
KEYS forecast:*
|
||||
|
||||
# Get cache stats
|
||||
GET forecast:cache:stats
|
||||
|
||||
# Clear cache (if needed)
|
||||
FLUSHDB
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔍 Monitoring
|
||||
|
||||
### View Metrics (Prometheus)
|
||||
|
||||
```bash
|
||||
# Production scheduler metrics
|
||||
curl http://localhost:8001/metrics | grep production_schedules
|
||||
|
||||
# Procurement scheduler metrics
|
||||
curl http://localhost:8002/metrics | grep procurement_plans
|
||||
|
||||
# Forecast cache metrics
|
||||
curl http://localhost:8003/metrics | grep forecast_cache
|
||||
```
|
||||
|
||||
### Key Metrics to Watch
|
||||
|
||||
```promql
|
||||
# Scheduler success rate (should be > 95%)
|
||||
rate(production_schedules_generated_total{status="success"}[5m])
|
||||
rate(procurement_plans_generated_total{status="success"}[5m])
|
||||
|
||||
# Cache hit rate (should be > 70%)
|
||||
forecast_cache_hit_rate
|
||||
|
||||
# Generation time (should be < 60s)
|
||||
histogram_quantile(0.95,
|
||||
rate(production_schedule_generation_duration_seconds_bucket[5m]))
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🐛 Debugging
|
||||
|
||||
### Check Scheduler Status
|
||||
|
||||
```python
|
||||
# In Python shell
|
||||
from app.services.production_scheduler_service import ProductionSchedulerService
|
||||
from app.core.config import settings
|
||||
|
||||
scheduler = ProductionSchedulerService(settings)
|
||||
await scheduler.start()
|
||||
|
||||
# Check configured jobs
|
||||
jobs = scheduler.scheduler.get_jobs()
|
||||
for job in jobs:
|
||||
print(f"{job.name}: next run at {job.next_run_time}")
|
||||
```
|
||||
|
||||
### View Scheduler Logs
|
||||
|
||||
```bash
|
||||
# Production scheduler
|
||||
kubectl logs -f deployment/production-service | grep -E "scheduler|schedule"
|
||||
|
||||
# Procurement scheduler
|
||||
kubectl logs -f deployment/orders-service | grep -E "scheduler|plan"
|
||||
|
||||
# Look for these patterns:
|
||||
# ✅ "Daily production planning completed"
|
||||
# ✅ "Production schedule created successfully"
|
||||
# ❌ "Error processing tenant production"
|
||||
# ⚠️ "Tenant processing timed out"
|
||||
```
|
||||
|
||||
### Test Timezone Handling
|
||||
|
||||
```python
|
||||
from shared.utils.timezone_helper import TimezoneHelper
|
||||
|
||||
# Get current date in different timezones
|
||||
madrid_date = TimezoneHelper.get_current_date_in_timezone("Europe/Madrid")
|
||||
ny_date = TimezoneHelper.get_current_date_in_timezone("America/New_York")
|
||||
tokyo_date = TimezoneHelper.get_current_date_in_timezone("Asia/Tokyo")
|
||||
|
||||
print(f"Madrid: {madrid_date}")
|
||||
print(f"NY: {ny_date}")
|
||||
print(f"Tokyo: {tokyo_date}")
|
||||
|
||||
# Check if business hours
|
||||
is_business = TimezoneHelper.is_business_hours(
|
||||
timezone_str="Europe/Madrid",
|
||||
start_hour=8,
|
||||
end_hour=20
|
||||
)
|
||||
print(f"Business hours: {is_business}")
|
||||
```
|
||||
|
||||
### Test Forecast Cache
|
||||
|
||||
```python
|
||||
from services.forecasting.app.services.forecast_cache import get_forecast_cache_service
|
||||
from datetime import date
|
||||
from uuid import UUID
|
||||
|
||||
cache = get_forecast_cache_service(redis_url="redis://localhost:6379/0")
|
||||
|
||||
# Check if available
|
||||
print(f"Cache available: {cache.is_available()}")
|
||||
|
||||
# Get cache stats
|
||||
stats = cache.get_cache_stats()
|
||||
print(f"Cache stats: {stats}")
|
||||
|
||||
# Test cache operation
|
||||
tenant_id = UUID("your-tenant-id")
|
||||
product_id = UUID("your-product-id")
|
||||
forecast_date = date.today()
|
||||
|
||||
# Try to get cached forecast
|
||||
cached = await cache.get_cached_forecast(tenant_id, product_id, forecast_date)

|
||||
```bash
|
||||
# Check if service is running
|
||||
ps aux | grep uvicorn
|
||||
|
||||
# Check if scheduler initialized
|
||||
grep "scheduled jobs configured" logs/production.log
|
||||
|
||||
# Restart service
|
||||
pkill -f "uvicorn app.main:app"
|
||||
uvicorn app.main:app --reload
|
||||
```
|
||||
|
||||
### Cache Not Working

|
||||
```bash
|
||||
# Check Redis connection
|
||||
redis-cli ping # Should return PONG
|
||||
|
||||
# Check Redis keys
|
||||
redis-cli DBSIZE # Should have keys
|
||||
|
||||
# Restart Redis (if needed)
|
||||
redis-cli SHUTDOWN
|
||||
redis-server --daemonize yes
|
||||
```
|
||||
|

## Scheduler Overview
|
||||
|
||||
| Scheduler | Time | What It Does |
|
||||
|-----------|------|--------------|
|
||||
| **Production** | 5:30 AM (tenant timezone) | Creates daily production schedules |
|
||||
| **Procurement** | 6:00 AM (tenant timezone) | Creates daily procurement plans |
|
||||
|
||||
**Critical:** Both schedulers MUST complete successfully every morning, or bakeries won't have production/procurement plans for the day!
|
||||
|
||||
---
|
||||
|
||||
## Common Incidents & Solutions
|
||||
|
||||
### 🔴 CRITICAL: Scheduler Completely Failed
|
||||
|
||||
**Alert:** `SchedulerUnhealthy` or `NoProductionSchedulesGenerated`
|
||||
|
||||
**Impact:** HIGH - No plans generated for any tenant
|
||||
|
||||
**Immediate Actions (< 5 minutes):**
|
||||
|
||||
```bash
|
||||
# 1. Check if service is running
|
||||
kubectl get pods -n production | grep production-service
|
||||
kubectl get pods -n orders | grep orders-service
|
||||
|
||||
# 2. Check recent logs for errors
|
||||
kubectl logs -n production deployment/production-service --tail=100 | grep ERROR
|
||||
kubectl logs -n orders deployment/orders-service --tail=100 | grep ERROR
|
||||
|
||||
# 3. Restart service if frozen/crashed
|
||||
kubectl rollout restart deployment/production-service -n production
|
||||
kubectl rollout restart deployment/orders-service -n orders
|
||||
|
||||
# 4. Wait 2 minutes for scheduler to initialize, then manually trigger
|
||||
curl -X POST http://production-service:8000/test/production-scheduler \
|
||||
-H "Authorization: Bearer $ADMIN_TOKEN"
|
||||
|
||||
curl -X POST http://orders-service:8000/test/procurement-scheduler \
|
||||
-H "Authorization: Bearer $ADMIN_TOKEN"
|
||||
```
|
||||
|
||||
**Follow-up Actions:**
|
||||
- Check RabbitMQ health (leader election depends on it)
|
||||
- Review database connectivity
|
||||
- Check resource limits (CPU/memory)
|
||||
- Monitor metrics for successful generation
|
||||
|
||||
---
|
||||
|
||||
### 🟠 HIGH: Single Tenant Failed
|
||||
|
||||
**Alert:** `DailyProductionPlanningFailed{tenant_id="abc-123"}`
|
||||
|
||||
**Impact:** MEDIUM - One bakery affected
|
||||
|
||||
**Immediate Actions (< 10 minutes):**
|
||||
|
||||
```bash
|
||||
# 1. Check logs for specific tenant
|
||||
kubectl logs -n production deployment/production-service --tail=500 | \
|
||||
grep "tenant_id=abc-123" | grep ERROR
|
||||
|
||||
# 2. Common causes:
|
||||
# - Tenant database connection issue
|
||||
# - External service timeout (Forecasting, Inventory)
|
||||
# - Invalid data (e.g., missing products)
|
||||
|
||||
# 3. Manually retry for this tenant
|
||||
curl -X POST http://production-service:8000/test/production-scheduler \
|
||||
-H "Authorization: Bearer $ADMIN_TOKEN"
|
||||
# (Scheduler will skip tenants that already have schedules)
|
||||
|
||||
# 4. If still failing, check tenant-specific issues:
|
||||
# - Verify tenant exists and is active
|
||||
# - Check tenant's inventory has products
|
||||
# - Check forecasting service can access tenant data
|
||||
```
|
||||
|
||||
**Follow-up Actions:**
|
||||
- Contact tenant to understand their setup
|
||||
- Review tenant data quality
|
||||
- Check if tenant is new (may need initial setup)
|
||||
|
||||
---
|
||||
|
||||
### 🟡 MEDIUM: Scheduler Running Slow
|
||||
|
||||
**Alert:** `production_schedule_generation_duration_seconds > 120s`
|
||||
|
||||
**Impact:** LOW - Scheduler completes but takes longer than expected
|
||||
|
||||
**Immediate Actions (< 15 minutes):**
|
||||
|
||||
```bash
|
||||
# 1. Check current execution time
|
||||
kubectl logs -n production deployment/production-service --tail=100 | \
|
||||
grep "production planning completed"
|
||||
|
||||
# 2. Check database query performance
|
||||
# Look for slow query logs in PostgreSQL
|
||||
|
||||
# 3. Check external service response times
|
||||
# - Forecasting Service health: curl http://forecasting-service:8000/health
|
||||
# - Inventory Service health: curl http://inventory-service:8000/health
|
||||
# - Orders Service health: curl http://orders-service:8000/health
|
||||
|
||||
# 4. Check CPU/memory usage
|
||||
kubectl top pods -n production | grep production-service
|
||||
kubectl top pods -n orders | grep orders-service
|
||||
```
|
||||
|
||||
**Follow-up Actions:**
|
||||
- Consider increasing timeout if consistently near limit
|
||||
- Optimize slow database queries
|
||||
- Scale external services if overloaded
|
||||
- Review tenant count (may need to process fewer in parallel)
|
||||
|
||||
---
|
||||
|
||||
### 🟡 MEDIUM: Low Forecast Cache Hit Rate
|
||||
|
||||
**Alert:** `ForecastCacheHitRateLow < 50%`
|
||||
|
||||
**Impact:** LOW - Increased load on Forecasting Service, slower responses
|
||||
|
||||
**Immediate Actions (< 10 minutes):**
|
||||
|
||||
```bash
|
||||
# 1. Check Redis is running
|
||||
kubectl get pods -n redis | grep redis
|
||||
redis-cli ping # Should return PONG
|
||||
|
||||
# 2. Check cache statistics
|
||||
curl http://forecasting-service:8000/api/v1/{tenant_id}/forecasting/cache/stats \
|
||||
-H "Authorization: Bearer $ADMIN_TOKEN"
|
||||
|
||||
# 3. Check cache keys
|
||||
redis-cli KEYS "forecast:*" | wc -l # Should have many entries
|
||||
|
||||
# 4. Check Redis memory
|
||||
redis-cli INFO memory | grep used_memory_human
|
||||
|
||||
# 5. If cache is empty or Redis is down, restart Redis
|
||||
kubectl rollout restart statefulset/redis -n redis
|
||||
```
|
||||
|
||||
**Follow-up Actions:**
|
||||
- Monitor cache rebuild (should hit ~80-90% within 1 day)
|
||||
- Check Redis configuration (memory limits, eviction policy)
|
||||
- Review forecast TTL settings
|
||||
- Check for cache invalidation bugs
|
||||
|
||||

|
||||
|
||||
### 🟢 LOW: Plan Rejected by User
|
||||
|
||||
**Alert:** `procurement_plan_rejections_total` increasing
|
||||
|
||||
**Impact:** LOW - Normal user workflow
|
||||
|
||||
**Actions (< 5 minutes):**
|
||||
|
||||
```bash
|
||||
# 1. Check rejection logs for patterns
|
||||
kubectl logs -n orders deployment/orders-service --tail=200 | \
|
||||
grep "plan rejection"
|
||||
|
||||
# 2. Check if auto-regeneration triggered
|
||||
kubectl logs -n orders deployment/orders-service --tail=200 | \
|
||||
grep "Auto-regenerating plan"
|
||||
|
||||
# 3. Verify rejection notification sent
|
||||
# Check RabbitMQ queue: procurement.plan.rejected
|
||||
|
||||
# 4. If rejection notes mention "stale" or "outdated", plan will auto-regenerate
|
||||
# Otherwise, user needs to manually regenerate or modify plan
|
||||
```
|
||||
|
||||
**Follow-up Actions:**
|
||||
- Review rejection reasons for trends
|
||||
- Consider user training if many rejections
|
||||
- Improve plan accuracy if consistent issues

## Metrics to Monitor
|
||||
|
||||
### Production Scheduler
|
||||
|
||||
```promql
|
||||
# Success rate (should be > 95%)
|
||||
rate(production_schedules_generated_total{status="success"}[5m]) /
|
||||
rate(production_schedules_generated_total[5m])
|
||||
|
||||
# Average generation time (should be < 60s)
|
||||
histogram_quantile(0.95,
|

## Log Patterns to Watch
|
||||
|
||||
### Success Patterns
|
||||
|
||||
```
|
||||
✅ "Daily production planning completed" - All tenants processed
|
||||
✅ "Production schedule created successfully" - Individual tenant success
|
||||
✅ "Forecast cache HIT" - Cache working correctly
|
||||
✅ "Production scheduler service started" - Service initialized
|
||||
```
|
||||
|
||||
### Warning Patterns
|
||||
|
||||
```
|
||||
⚠️ "Tenant processing timed out" - Individual tenant taking too long
|
||||
⚠️ "Forecast cache MISS" - Cache miss (expected some, but not all)
|
||||
⚠️ "Approving plan older than 24 hours" - Stale plan being approved
|
||||
⚠️ "Could not fetch tenant timezone" - Timezone configuration issue
|
||||
```
|
||||
|
||||
### Error Patterns
|
||||
|
||||
```
|
||||
❌ "Daily production planning failed completely" - Complete failure
|
||||
❌ "Error processing tenant production" - Tenant-specific failure
|
||||
❌ "Forecast cache Redis connection failed" - Cache unavailable
|
||||
❌ "Migration version mismatch" - Database migration issue
|
||||
❌ "Failed to publish event" - RabbitMQ connectivity issue
|
||||
```

## Escalation Procedure
|
||||
|
||||
### Level 1: DevOps On-Call (0-30 minutes)
|
||||
|
||||
- Check service health
|
||||
- Review logs for obvious errors
|
||||
- Restart services if crashed
|
||||
- Manually trigger schedulers if needed
|
||||
- Monitor for resolution
|
||||
|
||||
### Level 2: Backend Team (30-60 minutes)
|
||||
|
||||
- Investigate complex errors
|
||||
- Check database issues
|
||||
- Review scheduler logic
|
||||
- Coordinate with other teams (if external service issue)
|
||||
|
||||
### Level 3: Engineering Lead (> 60 minutes)
|
||||
|
||||
- Major architectural issues
|
||||
- Database corruption or loss
|
||||
- Multi-service cascading failures
|
||||
- Decisions on emergency fixes vs. scheduled maintenance

## Testing After Deployment
|
||||
|
||||
### Post-Deployment Checklist
|
||||
|
||||
```bash
|
||||
# 1. Verify services are running
|
||||
kubectl get pods -n production
|
||||
kubectl get pods -n orders
|
||||
|
||||
# 2. Check health endpoints
|
||||
curl http://production-service:8000/health
|
||||
curl http://orders-service:8000/health
|
||||
|
||||
# 3. Verify schedulers are configured
|
||||
kubectl logs -n production deployment/production-service | \
|
||||
grep "scheduled jobs configured"
|
||||
|
||||
# 4. Manually trigger test run
|
||||
curl -X POST http://production-service:8000/test/production-scheduler \
|
||||
-H "Authorization: Bearer $ADMIN_TOKEN"
|
||||
|
||||
curl -X POST http://orders-service:8000/test/procurement-scheduler \
|
||||
-H "Authorization: Bearer $ADMIN_TOKEN"
|
||||
|
||||
# 5. Verify test run completed successfully
|
||||
kubectl logs -n production deployment/production-service | \
|
||||
grep "Production schedule created successfully"
|
||||
|
||||
kubectl logs -n orders deployment/orders-service | \
|
||||
grep "Procurement plan generated successfully"
|
||||
|
||||
# 6. Check metrics dashboard
|
||||
# Visit: http://grafana:3000/d/production-planning
|
||||
```

## Known Issues & Workarounds
|
||||
|
||||
### Issue: Scheduler runs twice in distributed setup
|
||||
|
||||
**Symptom:** Duplicate schedules/plans for same tenant and date
|
||||
|
||||
**Cause:** Leader election not working (RabbitMQ connection issue)
|
||||
|
||||
**Workaround:**
|
||||
```bash
|
||||
# Temporarily scale to single instance
|
||||
kubectl scale deployment/production-service --replicas=1 -n production
|
||||
kubectl scale deployment/orders-service --replicas=1 -n orders
|
||||
|
||||
# Fix RabbitMQ connectivity
|
||||
# Then scale back up
|
||||
kubectl scale deployment/production-service --replicas=3 -n production
|
||||
kubectl scale deployment/orders-service --replicas=3 -n orders
|
||||
```
|
||||
|
||||
### Issue: Timezone shows wrong time
|
||||
|
||||
**Symptom:** Schedules generated at wrong hour
|
||||
|
||||
**Cause:** Tenant timezone not configured or incorrect
|
||||
|
||||
**Workaround:**
|
||||
```sql
|
||||
-- Check tenant timezone
|
||||
SELECT id, name, timezone FROM tenants WHERE id = '{tenant_id}';
|
||||
|
||||
-- Update if incorrect
|
||||
UPDATE tenants SET timezone = 'Europe/Madrid' WHERE id = '{tenant_id}';
|
||||
|
||||
-- Verify server uses UTC
|
||||
-- In container: date (should show UTC)
|
||||
```
|
||||
|
||||
### Issue: Forecast cache always misses
|
||||
|
||||
**Symptom:** `forecast_cache_hit_rate = 0%`
|
||||
|
||||
**Cause:** Redis not accessible or REDIS_URL misconfigured
|
||||
|
||||
**Workaround:**
|
||||
```bash
|
||||
# Check REDIS_URL environment variable
|
||||
kubectl get deployment forecasting-service -n forecasting -o yaml | \
|
||||
grep REDIS_URL
|
||||
|
||||
# Should be: redis://redis:6379/0
|
||||
|
||||
# If incorrect, update:
|
||||
kubectl set env deployment/forecasting-service \
|
||||
REDIS_URL=redis://redis:6379/0 -n forecasting
|
||||
```
