It's usually something like

 	monc->clog.debug() << "hi there\n";

Looks like in the current code, the clog generated by OSD and MDS are
not sent to MON. When the client subscribes to the log monitor, it
won't get the OSD and MDS clogs. It only gets those generated by MON.

Most likely, you need to set 'clog_to_monitors' (or unset it if you
changed it).

When 'clog_to_monitors' is set, we queue the log entry to LogClient.
However, we only send the log to monitor through the loopback
connection when the LogClient itself is MON. For OSD and MDS, we don't
send the logs even if 'clog_to_monitors' is set.
