Doc Type: Bug Fix
Doc Text:
.Ceph log messages are now LOG_INFO priority Previously, Ceph log messages had the `LOG_DEBUG` priority. However, with the default `syslog` configuration, `LOG_DEBUG` messages do not appear in the logs. With this update, Ceph log messages have `LOG_INFO` priority, ensuring that they appear in the logs.

Description Brad Hubbard 2016-09-23 03:55:55 UTC
Description of problem:

When we resolved Bug #13993 to stop everything sent to syslog being sent at LOG_EMERG priority it was decided LOG_DEBUG was the appropriate level. In hindsight I believe this was the wrong decision and that LOG_INFO is a better choice.

With a default syslog configuration syslog messages sent at LOG_DEBUG priority do not make it to the logs, since by default syslog logs everything of info level or higher. So, in order to see syslog messages from Ceph (including logs generated in the event of as crash) currently requires configuring Ceph to log to syslog and also configuring syslog (or rsyslog) to display debug messages.

The problem can be demonstrated on a system with syslog configured using the following.

    logger -p user.info "This should go to syslog"
    logger -p user.debug "This should not go to syslog"
    grep "to syslog" /var/log/messages
    May 10 02:22:02 intel-boxen-02 root: This should go to syslog

The move to journalctl will make this less of an issue IMHO but that may take a while to be the default in all environments.
