Collection of scripts to be used with the Collectd Exec Plugin.
Each scripts consists of an executable script collecting the data, a configuration file for Collectd and a data-set specification.
- gridengine-jobs.rb queries a GridEngine queue master for the number of jobs running, queued and suspended.
- infiniband-traffic.rb collects the counters from a Infiniband network card using perfquery.
- lustre-ls-runtime.rb monitors the response time of a Lustre file-system for listing a random set of files. In case Lustre doesn't respond to a ls within a timeout a spike in the data is produced.
- ipmi-temperature.rb collects the system temperature using ipmitool.
These instructions cover Debian Squeeze, but should be easy to adapt to other Linux distributions.
Optional configurations for Collectd plug-ins are automatically
read from /etc/collectd/collectd.d/, copy *.conf and
*.db into this directory. The executable scripts need to be
deployed to /usr/lib/collectd/exec. After deployment
restart the Collectd daemon. Check if the daemon has resumed
normal operation by looking to the log-file.
» /etc/init.d/collectd restart
» cat /var/log/collectd.log
...SNIP...
[2012-08-29 16:34:37] Initialization complete, entering read-loop.
» ls /var/lib/collectd/rrd/$(hostname -f)/ipmi
ipmi_temperature.rrd
If everything works as expected you should find a new RRD file for the values collected by a script. The example above shows where to find a corresponding file for the IPMI temperature script.
Depending on the script it may be necessary to configure Sudo to allow the monitoring user to execute commands limited to root. All configuration files inside this repository require a user called "mon" for this purpose.
You can add a file to the /etc/sudoers.d/ directory to enable "mon" to execute a certain command. The following example illustrates this for the ipmitool command:
» echo "mon $(hostname -f) = NOPASSWD: /usr/bin/ipmitool" > /etc/sudoers.d/ipmitool
» chmod 0440 /etc/sudoers.d/ipmitool
