openMosixcollector


The openMosixcollector is a daemon which should/could be started on one cluster-member.
It logs the openMosix-load of each node to the directory /tmp/openmosixcollector/*
These history log-files analyzed by the openMosixanalyzer (as described later)
gives an nonstop overview of the load, memory and processes in your cluster.
There is one main log-file called /tmp/openmosixcollector/cluster
Additional to this there are additional files in this directory to which the
data is written.

At startup the openMosixcollector writes its PID (process id) to
/var/run/openMosixcollector.pid

The openMosixcollector-daemon restarts every 12 hours and saves the current history to
/tmp/openmosixcollector[date]/*
These backups are done automatically but you can also trigger this manual.

There is an option to write a checkpoint to the history.
These checkpoints are graphically marked as a blue vertical line if you analyze
the history log-files with the openMosixanalyzer.
For example you can set a checkpoint when you start a job on your cluster
and another one at the end..

Here is the explanation of the possible commandline-arguments:
  • openmosixcollector -d      //starts the collector as a daemon
  • openmosixcollector -k      //stops the collector
  • openmosixcollector -n      //writes a checkpoint to the history
  • openmosixcollector -r      //saves the current history and starts a new one
  • openmosixcollector         //print out a short help


  • You can start this daemon whith its init-script in /etc/init.d or /etc/rc.d/init.d.
    You just have to create a symbolic link to one of the runlevels for automatic startup.

    How to analyze the created logfiles is described in the openMosixanalyzer-section.
