Did you do something like this Getting keys with ceph daemon mon.a config show | grep debug_ | grep mgr ceph tell mon.* injectargs --$monk=0/0
Any input from anyone, please?
This part of Ceph is very poorly documented. Perhaps there's a better place to ask this question? Please let me know.

Hi!
I am still fighting excessive logging. I've reduced unnecessary logging from most components except for mon audit: https://pastebin.com/jjWvUEcQ
How can I stop logging this particular type of messages?
I would appreciate your help and advice.

Thank you for your response, Igor.
Currently debug_rocksdb is set to 4/5:
# ceph config get osd debug_rocksdb 4/5
This setting seems to be default. Is my understanding correct that you're suggesting setting it to 3/5 or even 0/5? Would setting it to 0/5 have any negative effects on the cluster?

Hi Zakhar,
do reduce rocksdb logging verbosity you might want to set debug_rocksdb to 3 (or 0).
I presume it produces a significant part of the logging traffic.
Thanks,

Hi,
Our Ceph 16.2.x cluster managed by cephadm is logging a lot of very detailed messages, Ceph logs alone on hosts with monitors and several OSDs has already eaten through 50% of the endurance of the flash system drives over a couple of years.
Cluster logging settings are default, and it seems that all daemons are writing lots and lots of debug information to the logs, such as for example: https://pastebin.com/ebZq8KZk (it's just a snippet, but
lots and lots of various information).
Is there a way to reduce the amount of logging and, for example,

logging to warnings or important messages so that it doesn't include every successful authentication attempt, compaction etc, etc, when the cluster is healthy and operating normally?
I would very much appreciate your advice on this.
Best regards, Zakhar
