Re: Migrated to cephadm, rgw logs to file even when rgw_ops_log_rados is true

I haven't played with rgw_ops yet, but have you looked at the various syslog config options?

ceph config ls | grep syslog
log_to_syslog
err_to_syslog
clog_to_syslog
clog_to_syslog_level
clog_to_syslog_facility
mon_cluster_log_to_syslog
mon_cluster_log_to_syslog_level
mon_cluster_log_to_syslog_facility

Maybe one of them is what you're looking for.

Hi!
Currently I have limitted the optput of rgw log to syslog from rsyslog (as
suggested by
Anthony), limitted docker logs from daemon.json.
I still get ops logs written to both logs pool and ops log file
(ops-log-ceph-client.rgw.hostname.log).

How to stop logging ops log on rgw disk and keep logs on logs pool?
Current config:
global                                                advanced  debug_rgw
                                    0/0
global                                                advanced
 rgw_enable_ops_log                         true
global                                                advanced
 rgw_ops_log_rados                           true

Thank you!

Hi,
we recently migrated to cephadm from ceph-deploy a 18.2.2 ceph cluster
(Ubuntu with docker).
RGWs are separate vms.
We noticed syslog increased a lot due to rgw's access logs sent to it.
And because we use to log ops, a huge ops log file on
/var/log/ceph/cluster-id/ops-log-ceph-client.rgw.hostname-here.log.

While having "rgw_ops_log_rados": "true", oplogs goes to both file and
rados pool for logs.
If false it doesn't log anything, as expected.
How to stop dockered rgws to log to syslog and to a file on disk, but to
keep opslog in logs pool?

Config is:
global                                                basic
log_to_journald                                  false
global                                                advanced
 rgw_enable_ops_log                      false
global                                                advanced
 rgw_ops_log_rados                        true

A few hours later after after enabling it back, after massive cleanup, it
does logging ops but only to files.
How to get ops logs in rados pool and access log to a file on disk but not
on syslog?
I have add this to daemon.json to limit access logs to accumulate on
/var/log/docker/containers/rand/rand/json.log file:

{
  "log-driver": "local",
  "log-opts": {
    "max-size": "512m",
    "max-file": "3"
  }
}


Thank you!
Paul
