-= SETUP NOTES =-

Copy this file to your Nagios installation folder in "libexec/". Rename to "check_dell_openmanage.pl".

You must have Dell OpenManage installed on the server you wish to monitor. You must have enabled SNMP on the server and allow SNMP queries. On the nagios server that will be running the plugin you must have the perl "Net::SNMP" module installed.

perl -MCPAN -e shell
cpan> install Net::SNMP

Check Dell OpenManage locally on the monitored host for alert threshholds like min/max fan speeds...

To do a test run using SNMPv1 try:

./check_dell_openmanage.pl -H 192.168.1.250 -C public -T test

This will report which OID's your system supports.

"custom" is meant to be customised by advanced users

-= TODO =-

* Fix bugs and make more user friendly.

-= REVISION =-

ver 1.3
* If non-numeric codes are returned just add the text to the statusinfo
* This was done to allow adding machine information Dell Model Number and Service Tag to output.

ver 1.2
*major rewrite. simplified the way new systems are defined.
*added system type "test" which can be used to easly generate new system definitions.

ver 1.1
*formating of text output
*add blade system type... blades apparently do not support systemStatePowerSupplyStatusCombined,
systemStateCoolingDeviceStatusCombined or systemStateChassisIntrusionStatusCombined

ver 1.0
*while in verbose mode report which OID failed in a more readable manner.
*add "global", "chassis", and "custom" system type.
*removed system type pe2950.

ver 0.9
*added type dellom_storage as this is more accurate. this plugin works with all PowerEdge servers it has been tested with. left pe2950 type in for compatibility.
*remove min max int options from help text as they are no longer relevant

ver 0.8
*check that perl environment has "Net::SNMP" if not found complain.
missing "Net::SNMP" is the most common issue users report.

ver 0.7
*removed ucdavis definition. Added note about SNMPv3 dependencies
