System Health and Monitoring

Project Deku includes comprehensive monitoring and health checking capabilities to ensure reliable operation and quick issue resolution.

Health Check System

Health Check Endpoint

Primary Health Check: - URL: /dashboards/health/ - Method: GET - Expected Response: HTTP 200 with system status - Use Case: Load balancer health checks, monitoring systems

Component Health Monitoring

Database Health: - Connection pool status and utilization - Query performance and slow query detection - Database lock monitoring and deadlock detection - Storage utilization and growth trends

Redis Health: - Memory usage and eviction policies - Connection counts and client statistics - Key expiration and cleanup operations - Replication status (if applicable)

Celery Task Queue: - Worker process status and resource usage - Task execution rates and queue lengths - Failed task monitoring and retry logic - Worker memory usage and restart requirements

External Integrations: - ODK Central connectivity and API response times - KoBoToolbox connectivity and authentication status - Azure Storage connectivity and upload/download performance - Kachu transcription service availability

System Monitoring Dashboard

Real-time Metrics

Performance Indicators: - Request Response Times: Average, p95, p99 response times - Error Rates: HTTP error rates by endpoint and status code - Database Performance: Query execution times and connection utilization - Background Jobs: Task processing rates and queue backlogs - Resource Utilization: CPU, memory, and disk usage trends

Alert Configuration

Critical Alerts (Immediate Response Required): - Database connection failures or high error rates - Application server crashes or memory exhaustion - Background job processing completely stopped - Security incidents or unauthorized access attempts - Data corruption or validation failure spikes

Warning Alerts (Investigation Required): - Slow response times exceeding thresholds - High resource utilization (>80% CPU, memory, disk) - Background job queue backlog building up - External integration intermittent failures - Unusual user activity patterns

Troubleshooting Common Issues

Application Issues

Authentication Problems: - Symptoms: Users cannot log in or access restricted areas - Diagnosis: Check authentication logs, session storage, user permissions - Resolution: Reset sessions, verify user accounts, check authentication configuration

Data Sync Issues: - Symptoms: Survey data not appearing or outdated information - Diagnosis: Check ODK/KoBo connectivity, review sync logs, verify credentials - Resolution: Re-authenticate services, force manual sync, check firewall rules

Performance Issues: - Symptoms: Slow page loads or timeout errors - Diagnosis: Check database performance, review resource utilization, analyze logs - Resolution: Optimize queries, increase resources, implement caching

Infrastructure Issues

Database Problems: - Connection Issues: Check connection pool settings and network connectivity - Performance Issues: Analyze slow queries and implement optimization - Storage Issues: Monitor disk space and implement cleanup procedures

Background Job Issues: - Queue Backlog: Check Celery worker status and resource availability - Task Failures: Review error logs and fix underlying issues - Resource Exhaustion: Monitor worker memory usage and implement limits

Integration Problems: - API Failures: Check external service status and authentication - Network Issues: Verify firewall rules and DNS resolution - Rate Limiting: Implement proper retry logic and respect API limits
