Hi, all
In our documentation, it says that:
Ceph’s logging levels operate on a scale of 1 to 20, where 1
is terse and 20 is verbose.
http://docs.ceph.com/docs/master/rados/troubleshooting/log-and-debug/#subsystem-log-and-debug-settings
But, it seems that there are some logging levels 25 :
mds/MDBalancer.cc:276: dout(25) << "=== got heartbeat " <<
m->get_beat() << " from " << m->get_source().num() << " " <<
m->get_load() << dendl;
mds/CInode.cc:4189: dout(25) << __func__ << dendl;
mds/MDCache.cc:11656: //dout(25) << "saw depth " << d << " " <<
*dir << dendl;
mds/MDCache.cc:11666: //dout(25) << " saw sub " << **p << dendl;
mds/journal.cc:373: dout(25) << "EMetaBlob::add_dir_context(" <<
dir << ") maybe " <<
So, shoud we update our documentation, or update logging level to 20?
I've seen douts on levels as high as 35, so if this is really concerning, we could update docs to reflect the fact that level 20 is usually the
most verbose, with some rare exceptions that may be useful for devs with deep knowledge of Ceph code or devs responsible for particular piece of
code.
