A user asked on the openshift-sme mailing list:

I wonder if there is any "official" diagram for those stack like the one in https://docs.openshift.com/container-platform/4.9/monitoring/monitoring-overview.html#understanding-the-monitoring-stack_monitoring-overview.

Response:

For logging, perhaps, it's useful for you this document:

For the new stack for logging, if you need it, another document exists. Let me know if you need it.
