# Health Monitoring for Self-Hosted Instances
This PR implements basic health monitoring for self-hosted instances in
the admin panel.
## Service Status Checks
We're adding real-time health checks for:
- Redis Connection
- Database Connection
- Worker Status
- Message Sync Status
## Existing Functionality
We already have message sync and captcha counters that store aggregated
metrics in cache within a configurable time window (default: 5 minutes).
## New Endpoints
1. `/healthz` - Basic server health check for Kubernetes pod monitoring
2. `/healthz/{serviceName}` - Individual service health checks (returns
200 if healthy)
3. `/metricsz/{metricName}` - Time-windowed metrics (message sync,
captcha)
4. GraphQL resolver in admin panel for UI consumption
All endpoints use the same underlying service, with different
presentation layers for infrastructure and UI needs.
