This topic summarizes key auditable events in PKS, and the content of the log entries that the events generate. Operators can use this information to audit event logs to see what users took what actions at what times. This is helpful for security, compliance, and troubleshooting.

Log content can either be downloaded or configured to be transported via syslog.

PKS API events

The following log entry examples are produced by PKS API events and correspond to key actions taken by a user logged into the PKS CLI.

Kubernetes Audit Log Events

The Kubernetes control plane emits a standard log format every time a user takes action to query or change the state of the Kubernetes API. An example audit event log entry is below.
