Unexpected audit logs from system:admin user in system:masters group

Issue

After configuring OpenShift's Kubernetes API audit logs to collect all accesses from users in the system:masters group, there are a number of requests coming from the system:admin user.

This should not be happening as the system:admin user is protected within our company and we are not making normal users members of the system:masters group.

Every day at the same time of day the system:admin user performs 4 GET requests on the following API endpoints:

• /apis/config.openshift.io/v1/clusteroperators/etcd
• /apis/config.openshift.io/v1/clusteroperators/kube-scheduler
• /apis/config.openshift.io/v1/clusteroperators/kube-controller-manager
• /apis/config.openshift.io/v1/clusteroperators/kube-apiserver

Have the system:admin credentials been compromised and is this a security concern?
