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? /Z On Wed, 4 Oct 2023 at 21:23, Igor Fedotov <igor.fedotov@xxxxxxxx> wrote: > 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, > > Igor > > On 04/10/2023 20:51, Zakhar Kirpichenko wrote: > > Any input from anyone, please? > > > > On Tue, 19 Sept 2023 at 09:01, Zakhar Kirpichenko <zakhar@xxxxxxxxx> > wrote: > > > >> 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 > there's > >> lots and lots of various information). > >> > >> Is there a way to reduce the amount of logging and, for example, limit > the > >> 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 > >> > >> > >> > > _______________________________________________ > > ceph-users mailing list -- ceph-users@xxxxxxx > > To unsubscribe send an email to ceph-users-leave@xxxxxxx > _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
