Configuring logging in configuration file

Configure Ceph subsystems to log information, warning, and error messages to the log file.

About this task

You can specify the debugging level in the Ceph configuration file, which is found by default in /etc/ceph/ceph.conf.

For more information, see:

Procedure

To activate the Ceph debugging output dout() at boot time, add the debugging settings to the Ceph configuration file.
  1. For subsystems common to each daemon, add the settings under the [global] section.
  2. For subsystems for particular daemons, add the settings under a daemon section, such as [mon], [osd], or [mds].
    For example,
    [global]
            debug_ms = 1/5

    [mon]
            debug_mon = 20
            debug_paxos = 1/5
            debug_auth = 2

    [osd]
            debug_osd = 1/5
            debug_monc = 5/20

    [mds]
            debug_mds = 1
