Hi
If you are referring to monitoring usage for OAC then please check Accessing Metrics for OAC doc: https://docs.oracle.com/en/cloud/paas/analytics-cloud/acoci/metrics-oracle-analytics-cloud.html
If you are referring to end user usage, then you can enable Usage Tracking and/or enable Audit Logs for OAC https://docs.oracle.com/en/cloud/paas/analytics-cloud/acoci/monitor-logs.html.
Thanks
