check_lsi_raid - Nagios/Icinga plugin to check LSI RAID Controllers

WARNING

Running this plugin at a low time frame frequently (e.g. every 1/5/10 minutes) the controller suffers from performance issues! Most of the time is might be sufficient to check the status of controller and disks once a day to not affect performance but also get a decent monitoring. Cf. #42

General

• The LSI RAID Monitoring Plugin is a Nagios/Icinga to check the LSI RAID Controller for warnings or critical errors.
• It is written in Perl and uses the storage command line tool storcli to interact with the RAID Controller.

Current Version

• The current version of the check_lsi_raid plugin is available at the Thomas-Krenn github account: https://github.com/thomas-krenn/check_lsi_raid

Installation Requirements

• libfile-which-perl
• storcli

Requirements for Icinga/Nagios

• On the system to be monitored:
  • check_lsi_raid plugin
  • storcli
  • sudoers entry for user nagios and storcli (example: nagios ALL=(root) NOPASSWD:/usr/sbin/storcli)
• NRPE (optional): command definition
• On the Icinga-server:
  • command definition
  • service definition

Installation hints for CentOS

• It is possible that the NRPE daemon runs as user 'nrpe'. If that's the case you have to change the user in the sudoers entry.
• It may be necessary to specify the perl interpreter explicitly in the NRPE command definition, e.g.: command[check_lsi_raid]=/usr/lib/nagios/plugins/check_lsi_raid -C 0 -p /usr/sbin/storcli
• On newer CentOS/RedHat systems problems with sudo/SELinux might occur. In order to run the plugin as root the following sudoers options might help: Defaults:nrpe !requiretty Further more cf. #7

Parameter usage (example)

./check_lsi_raid -Tw 40 -Tc 50 -LD 0,1 -PD 1 -b 0
