Grafana Dashboards

PDB Operator includes pre-built Grafana dashboards for monitoring operator health and PDB status.

Prerequisites​

  • Prometheus scraping the operator (see Monitoring)
  • Grafana with a Prometheus data source configured

Available Dashboards​

The dashboard JSON files are located in config/grafana/dashboards/ in the pdb-operator repository.

Import Instructions​

Manual Import (UI)​

  1. Open Grafana and go to Dashboards > Import
  2. Upload the dashboard JSON file or paste its contents
  3. Select your Prometheus data source
  4. Click Import

Automated Import (API)​

curl -X POST http://localhost:3000/api/dashboards/db \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $GRAFANA_TOKEN" \
  -d @config/grafana/dashboards/pdb-operator-overview.json

Expected Metrics​

After importing, you should see data for:

  • Reconciliation duration and error rates
  • PDB creation/update/deletion rates
  • Active policies and managed deployments per namespace
  • Compliance status across workloads
  • Maintenance window activity

Troubleshooting​

No data showing​

  1. Verify Prometheus is scraping the operator metrics endpoint:

    kubectl get servicemonitor -n pdb-operator-system

  2. Check the Prometheus targets page for the pdb-operator target status

  3. Verify the data source is correctly configured in Grafana

Sample queries​

# Reconciliation error rate (last 5 minutes)
rate(pdb_operator_reconciliation_errors_total[5m])

# Currently managed deployments
pdb_operator_deployments_managed

# Active policies
pdb_operator_policies_active

# PDB operations per second
rate(pdb_operator_pdbs_created_total[5m]) + rate(pdb_operator_pdbs_updated_total[5m])
