Description:
you do not log the version of the agent or merlin when tomcat starts. This seems to be a mistake as it ensures that the information is visible and obvious. I would also recommend that you show the same information when you shutdown merlin or the agent since they may run for a long time and this information may no longer be in the log files.

How to repeat:
n/a

Suggested fix:
add the information to the log files during start up and shut down.

  EM-3356: log the mem version (and advisor version) on startup.

Note that the issue talks about both mem and agents; this commit is mem-only.

     : log the mem version (and advisor version) on startup.

The agent already logs it's version number on startup, although not on the default log level.
I'm opposed to also log it on shutdown, since even rotating the logs should not remove any logs.

For the agent the --version flag will show the version number:
./bin/mysql-monitor-agent --version

Created bug http://bugs.mysql.com/bug.php?id=45884 to track the agent request.

I don't know of a system that logs on shutdown. I agree with the 'log it on start up' bit, which is already fixed. But the 'log version on shutdown' is a bit strange.

Resolution:
Verified fixed in service manager build 2.1.0.1071.

A 'change' entry was added to the 2.1.0 changelog:

The version of Enterprise Monitor was not logged on startup.

Enterprise Monitor was changed to log the Monitor and Advisor version number on startup. See also Bug#45884.
