Cluster Auditor consists of a single Pod,
opa-collector, in the
cluster-auditor namespace. The first step to troubleshooting issues with Cluster Auditor would be to check the logs of that pod with
kubectl logs -l app=opa-exporter -n cluster-auditor -c opa-exporter and go from there.
You can also validate that all metrics are properly showing in Prometheus, see the monitoring document for more details on what to expect.
