Description Robert Sandu 2021-08-25 12:25:23 UTC

Description of problem:

As of [0] and [1], the CVO now runs in RHOCP 4.6 with `--v=5` log verbosity, which translates into 100 to 200k logs being generated daily by the CVO, most of which belong to:

1. The CVO syncing cluster manifests (i.e `sync_worker.go`).
2. The CVO logging `Throttling request took` messages (i.e. `request.go`).

Version-Release number of the following components: RHOCP 4.6 (GA and higher).

How reproducible: always

Steps to Reproduce:
1. standard CVO defaults in RHOCP 4.6 (GA and higher).

Actual results:
- 100 to 200k daily logs, putting additional disk I/O pressure on the cluster and Cluster Logging/Elasticsearch.

Expected results:
`Throttling request took` messages to not be logged.

The code for this is in https://github.com/kubernetes/client-go/blob/1bccfc8c60977e2ce3235394daff128996818f7b/rest/request.go#L577 and not part of CVO code.
