OpenShift metrics data is not being purged
Issue
- Per the documentation for OpenShift, it states that "By default, metrics data is stored for seven days. After seven days, Cassandra begins to purge the oldest metrics data." However,
/cassandra_datahas become 100% full multiple times on different clusters. It seems the purge is not happening after 7 days.
Environment
- OpenShift Container Platform (OCP) 3.6
