Sample Queries

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

# Average reconciliation duration (p95)
histogram_quantile(0.95, rate(pdb_operator_reconciliation_duration_seconds_bucket[5m]))

# Total managed deployments
sum(pdb_operator_deployments_managed)

# PDB operations per minute
sum(rate(pdb_operator_pdbs_created_total[5m]) + rate(pdb_operator_pdbs_updated_total[5m])) * 60

# Enforcement decisions by mode
sum by (enforcement_mode, decision_type) (rate(pdb_operator_enforcement_decisions_total[5m]))

# Non-compliant deployments
pdb_operator_compliance_status == 0
