Backup Exporter

The obmondo-backup-exporter chart deploys a Prometheus exporter that monitors the health of your backup infrastructure. It exposes metrics and ships PrometheusRule alerts for both Velero and PostgreSQL backups.

What It Monitors​

Backup SystemAlertFires When
PostgreSQLPostgresBackupExporterJobFailedA PostgreSQL backup job reports an error (backup_exporter_postgres_error == 1)
VeleroVeleroBackupExporterJobFailedA Velero backup job reports an error (backup_exporter_velero_error == 1)

Both alerts default to critical severity and fire after 5 minutes. These are configurable via the values file.

Deployment​

The chart is deployed via ArgoCD like any other KubeAid application. Key values to configure:

# Enable Prometheus alerting rules
prometheusRule:
  enabled: true
  postgres:
    enabled: true
    namespace: monitoring        # Where the PrometheusRule is created
    severity: critical
    alertForDuration: 5m
  velero:
    enabled: true
    namespace: monitoring
    severity: critical
    alertForDuration: 5m

The exporter also ships a ServiceMonitor for automatic Prometheus scraping and supports HorizontalPodAutoscaler configuration.

Integration with Existing Monitoring​

The backup exporter complements KubeAid's existing monitoring stack:

  • kube-prometheus scrapes the exporter's metrics via the ServiceMonitor
  • Alertmanager routes the backup failure alerts to your configured notification channels
  • Grafana can visualise the backup health metrics alongside your cluster dashboards
