Subject: [Nagiosplug-devel] Submission: check_insight / checking Compaq
Insight Agent status
Hi,
I've been looking to check the status/health of Compaq Insight Agents on
servers and found a spong plugin
(http://spong.sourceforge.net/downloads/plugins/spong-network/check_insi
ght) which I've slightly changed to work with Nagios.
I have pretty no idea of perl at all, just wanted to make it work for
me, so please don't shoot me for this copy-paste-code. I've tested some
basic things, it seems to work at least to report a warning if smthg is
degraded and OK of xcourse ;)
I'm also quite unsure if this is the right way to submit, so I'll just
try ;)
There're some "unknown" components on all servers I've checked so far,
if anybody has a documentation of what's exactly returned when getting
the OID 1.3.6.1.4.1.232.11.2.10.1.0 (CPQHOST_MIB isn't very descriptive)
I'd be happy to fix this.
