Description of problem:

On this page it says Fluentd buffer size can not be configured.
https://docs.openshift.com/container-platform/4.7/logging/cluster-logging-external.html

`You cannot adjust the buffer size or add a persistent volume claim (PVC) to the Fluentd daemon set or pods.`

However, On this page, it says Fluentd buffer can be configured.

https://docs.openshift.com/container-platform/4.7/logging/config/cluster-logging-collector.html#cluster-logging-collector-tuning_cluster-logging-collector

`The maximum size of the buffer, which is the total size of the stage and the queue. If the buffer size exceeds this value, Fluentd stops adding data to chunks and fails with an error. All data not in chunks is lost.`

This also impacts supported versions of OCP, so updating to 4.8 version.
Comment 9 Kathryn Alexander 2023-03-01 18:16:35 UTC 
All open BZs in this project will be migrated to Jira in the near future. Because this BZ has already been cloned into Jira, I am closing it now to reduce the number of duplicate Jiras.

This bug will be triaged for future work on the Jira issue that is shown in the Links section.
