Viewing the audit logs

You can view the logs for the OpenShift API server, Kubernetes API server, OpenShift OAuth API server, and OpenShift OAuth server for each control plane node.

Procedure

  • View the OpenShift API server audit logs:

    1. List the OpenShift API server audit logs that are available for each control plane node:

      $ oc adm node-logs --role=master --path=openshift-apiserver/
      Example output
      ci-ln-m0wpfjb-f76d1-vnb5x-master-0 audit-2021-03-09T00-12-19.834.log
ci-ln-m0wpfjb-f76d1-vnb5x-master-0 audit.log
ci-ln-m0wpfjb-f76d1-vnb5x-master-1 audit-2021-03-09T00-11-49.835.log
ci-ln-m0wpfjb-f76d1-vnb5x-master-1 audit.log
ci-ln-m0wpfjb-f76d1-vnb5x-master-2 audit-2021-03-09T00-13-00.128.log
ci-ln-m0wpfjb-f76d1-vnb5x-master-2 audit.log

    2. View a specific OpenShift API server audit log by providing the node name and the log name:

      $ oc adm node-logs <node_name> --path=openshift-apiserver/<log_name>

      For example:

      $ oc adm node-logs ci-ln-m0wpfjb-f76d1-vnb5x-master-0 --path=openshift-apiserver/audit-2021-03-09T00-12-19.834.log
      Example output
      {"kind":"Event","apiVersion":"audit.k8s.io/v1","level":"Metadata","auditID":"381acf6d-5f30-4c7d-8175-c9c317ae5893","stage":"ResponseComplete","requestURI":"/metrics","verb":"get","user":{"username":"system:serviceaccount:openshift-monitoring:prometheus-k8s","uid":"825b60a0-3976-4861-a342-3b2b561e8f82","groups":["system:serviceaccounts","system:serviceaccounts:openshift-monitoring","system:authenticated"]},"sourceIPs":["10.129.2.6"],"userAgent":"Prometheus/2.23.0","responseStatus":{"metadata":{},"code":200},"requestReceivedTimestamp":"2021-03-08T18:02:04.086545Z","stageTimestamp":"2021-03-08T18:02:04.107102Z","annotations":{"authorization.k8s.io/decision":"allow","authorization.k8s.io/reason":"RBAC: allowed by ClusterRoleBinding \"prometheus-k8s\" of ClusterRole \"prometheus-k8s\" to ServiceAccount \"prometheus-k8s/openshift-monitoring\""}}
