Useful Queries
Tracking the count of the cluster policies currently active:
count(count(kyverno_policy_rule_info_total{policy_type="cluster"} == 1) by (policy_name))Tracking the per-minute rate (avged over 30s) at which “validate” rules (both of cluster and namespaced policies) are being added to the cluster:
rate(kyverno_policy_rule_info_total{rule_type="validate"}[30s] == 1)*60Tracking the total number of mutate rules added in the last 24hrs:
count(kyverno_policy_rule_info_total{rule_type="mutate"}[24h]==1)Tracking the total number of active policies with enforce mode and background mode:
count(count(kyverno_policy_rule_info_total{policy_validation_mode="enforce", policy_background_mode="true"}==1) by (policy_name))
