Configure Alertmanager routing for ArgoCD application alerts
Added Alertmanager configuration to:
- Route ArgoCD application alerts to dedicated 'argocd-alerts' receiver
- Group ArgoCD alerts by alertname, name (app name), and severity
- Faster alert grouping for ArgoCD (10s wait vs 30s default)
- Repeat ArgoCD alerts every 6 hours
- Suppress Watchdog test alerts
- Configure inhibit rules to prevent alert spam
Alerts are visible in:
- Prometheus UI: http://localhost:9090/alerts
- Alertmanager UI: http://localhost:9093
- Grafana dashboard: ArgoCD Applications - Health & Sync Status
This ensures critical application issues are properly routed and visible
in the monitoring UI for immediate action.
