managarten/docker/grafana/dashboards/application-details.json
Till-JS 8c259a008b feat(monitoring): add comprehensive Grafana dashboards and alerting
New dashboards:
- Application Details: Node.js runtime (heap, event loop, GC),
  HTTP details (status codes, methods, top routes), error analysis
- Database Details: PostgreSQL and Redis metrics with detailed breakdowns

Alerting rules (docker/prometheus/alerts.yml):
- Service: down, high/very high error rate, slow response time
- Infrastructure: high CPU/memory/disk usage
- Database: PostgreSQL/Redis down, high connections, low cache hit
- Container: high CPU/memory, restarts

All dashboards include service selector variable for filtering.
