Description of problem:
Vector collector logs INFO messages every time it starts/stops watching a new file.
There are two problems with this
- it makes WARN/ERROR messages in the vector logs hard to see.
- It has a potentioally serious performance impact, the cost of writing the log to stderr for every file create/delete event is high compared to registering/unregsitering the file in memory. In a busy filesystem it may slow down the file watcher and cause missed events.
Version-Release number of selected component (if applicable):
Issue exists on current master branch, afffets all released 5.x versions to date.
How reproducible: 100%
Steps to Reproduce:
Run the collector, examine the logs:
oc logs -n openshift-logging -l component=collector
Actual results:
Many INFO messages like these:
