4.2. Viewing the audit log
You can view logs for the OpenShift Container Platform API server or the Kubernetes API server for each master node.
Procedure
To view the audit log:
View the OpenShift Container Platform API server logs
If necessary, get the node name of the log you want to view:
$ oc adm node-logs --role=master --path=openshift-apiserver/
Example output
ip-10-0-140-97.ec2.internal audit-2019-04-09T00-12-19.834.log ip-10-0-140-97.ec2.internal audit-2019-04-09T11-13-00.469.log ip-10-0-140-97.ec2.internal audit.log ip-10-0-153-35.ec2.internal audit-2019-04-09T00-11-49.835.log ip-10-0-153-35.ec2.internal audit-2019-04-09T11-08-30.469.log ip-10-0-153-35.ec2.internal audit.log ip-10-0-170-165.ec2.internal audit-2019-04-09T00-13-00.128.log ip-10-0-170-165.ec2.internal audit-2019-04-09T11-10-04.082.log ip-10-0-170-165.ec2.internal audit.log
View the OpenShift Container Platform API server log for a specific master node and timestamp or view all the logs for that master:
$ oc adm node-logs <node-name> --path=openshift-apiserver/<log-name>
For example:
$ oc adm node-logs ip-10-0-140-97.ec2.internal --path=openshift-apiserver/audit-2019-04-08T13-09-01.227.log
$ oc adm node-logs ip-10-0-140-97.ec2.internal --path=openshift-apiserver/audit.log
The output appears similar to the following:
Example output

View the Kubernetes API server logs:
If necessary, get the node name of the log you want to view:
$ oc adm node-logs --role=master --path=kube-apiserver/
Example output
ip-10-0-140-97.ec2.internal audit-2019-04-09T14-07-27.129.log ip-10-0-140-97.ec2.internal audit-2019-04-09T19-18-32.542.log ip-10-0-140-97.ec2.internal audit.log ip-10-0-153-35.ec2.internal audit-2019-04-09T19-24-22.620.log ip-10-0-153-35.ec2.internal audit-2019-04-09T19-51-30.905.log ip-10-0-153-35.ec2.internal audit.log ip-10-0-170-165.ec2.internal audit-2019-04-09T18-37-07.511.log ip-10-0-170-165.ec2.internal audit-2019-04-09T19-21-14.371.log ip-10-0-170-165.ec2.internal audit.log
View the Kubernetes API server log for a specific master node and timestamp or view all the logs for that master:

For example:
$ oc adm node-logs ip-10-0-140-97.ec2.internal --path=kube-apiserver/audit-2019-04-09T14-07-27.129.log
$ oc adm node-logs ip-10-0-170-165.ec2.internal --path=kube-apiserver/audit.log
