cmsetlog is a useful utility that sends MCSG log messages into a user specified log file in addition to the syslog facility. It’s a user contributed program, so it’ll be hiding in /usr/contrib/bin. You’ll have to use this program to support the philosophy of breaking out your syslog files (pls see Syslog daemon configuration), if you follow it.

You’ll have to figure out a way to reexecute this program every time the cluster or a node is restarted as the program doesn’t restart by default. That effort, though, is left as an exercise for the reader.

Desired results and command lines to achieve them follow:

  1. Log all MCSG messages to a specific log file as well as to the syslog facility.

    cmsetlog -f ${mcsg_log_file}
    
  2. Return to logging to the syslog facility only:

    cmsetlog -s
    
  3. After specifying a log file, request a greater level of detail:

    cmsetlog ${1-6}
    

    NOTE: Anything over 2 is going to start logging LOTS of information - to the point it’ll log heartbeat arrivals. Be careful of log sizes!

  4. Reset logging to the default level 0:

    cmsetlog -r
