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. .:: docs.google.com ::.
At startup the openMosixcollector writes its PID (process id) to /var/run/openMosixcollector.pid .:: telegra.ph ::.
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. .:: podcasts.apple.com ::. [What people say about JWT] [SciPy History]
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 with 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. .:: virtual-moodle.unne.edu.ar ::.
How to analyze the created logfiles is described in the openMosixanalyzer-section. .:: imgcredit.xyz ::.
