You're not doing anything wrong. Openmanage, when deployed on ESXi,
doesn't have the necessary capabilities for it to work.

Actually, the OID is 1.3.6.1.4.1.674.10892.5.4.300.10.1.9.1. I've toyed
around with this a bit, and for the most part you can simply replace
"1.3.6.1.4.1.674.10892.1" with "1.3.6.1.4.1.674.10892.5.4". Same goes for
storage OIDs, to a degree.

I have a modified prealpha version for testing, available in the test
branch in git:
http://git.uio.no/git/?p=check_openmanage.git;a=shortlog;h=refs/heads/test
Note that it's NOT production ready, I have only done some very limited
testing.
I had to simplify some stuff:
* Storage: The storage OIDs from the iDRAC7 are somewhat different,
compared to Openmanage. Some information that the plugin needs is
not available, such as numbered identifiers for components (used in
blacklisting). There are even some OIDs that aren't present in
Openmanage. In short, it's a mess, and the storage bit is very
simplistic. Perhaps the missing info will be added in a later
firmware release, we can only hope.
* ESM health OIDs are missing completely, so ESM health check is
omitted. Same for SD card check.
To use the new feature you have to specify '--idrac', like this:
check_openmanage --idrac -H
Test it, break it and tell me what you think :)
I've noticed that neither the rollup-status or component-status for
controllers catches that the controller is actually degraded from
out-of-date firmware. Hopefully it's an anomaly that doesn't apply to
other aspects of controllers, or other components.
