You can remove cluster logging from your OKD cluster.
You can stop log aggregation by deleting the Clusterlogging
custom resource (CR). After deleting the CR, there are other cluster logging components that remain, which you can optionally remove.
Deleting the Clusterlogging
CR does not remove the persistent volume claims (PVCs). To preserve or delete the remaining PVCs, persistent volumes (PVs), and associated data, you must take further action.
