• Version 3.7.3: This release fixes a couple of minor bug. The RPM name was changed and the RPM now requires all perl modules needed for extra functionality.
• Version 3.7.2: An option '--hide-servicetag', which will censor the serial number in the output, was added. A performance data bug was fixed for the amperage check.
• Version 3.7.1: A new blacklisting keyword 'pdisk_foreign' was added to allow blacklisting of foreign drives. A few minor bugs were fixed.

The main philosophy behind check_openmanage is that the plugin's output should be immediately useful to the system administrator. Great care has been taken to ensure that the output is accurate, compact and detailed enough to tell you exactly what you need to know in case of a hardware problem. It will identify blades and will not report "missing" power supplies, fans etc. on blade servers.

dell-server01 ~$ check_openmanage
OK - System: 'PowerEdge R710', SN: 'XXXXXXX', 72 GB ram (18 dimms), 1 logical drives, 2 physical drives

check_openmanage differs from other Dell plugins in the level of detail in the output. It tries to be as precise as possible about whatever is wrong. In most cases, it shouldn't be necessary to investigate further when you get an alert from check_openmanage.

nagios-server ~$ check_openmanage -H dell-server02
Physical Disk 1:3 [Seagate ST3300007LC, 300GB] on ctrl 0 needs attention: Failure Predicted

In addition, many options have been added to the plugin to let you decide for yourself how it should behave in your environment. You can blacklist components that you'll never fix, and control which of the components that are checked in the first place. The default setting is that almost everything is checked.

nagios-server ~$ check_openmanage -H dell-server03 -e
Memory module 4 [DIMM2_B, 1024 MB] needs attention: ECC single bit correction logging disabled
------ SYSTEM: PowerEdge 2850, SN: XXXXXXX

The plugin is designed to be used either locally with NRPE, or remotely via SNMP. In either case, it relies entirely on the Dell OpenManage System Administrator (OMSA) management software and cannot function if OMSA is not installed and running on the monitored system.

check_openmanage has been testet on a variety of Dell servers running RHEL3, RHEL4, RHEL5, RHEL6, VmWare ESX and various Windows releases, with recent OMSA versions. It may work with old versions of OMSA, and should work on other operating systems providing a fairly recent and functioning OMSA version.
