checking for reboots of a host (perhaps via SNMP/uptime?)

[Gregg Strickland]

Maybe put something in cron that sends a heartbeat to Nagios for a passive
service check called REBOOT saying everything is ok, then put an init script
that tells that same service that it is critical.  You would get the log
that it was critical showing a reboot, then the heartbeat would come along
and reset the status for you.

There might be a better way, but that's just off the top of my head.....

Subject: [Nagios-users] checking for reboots of a host (perhaps via
SNMP/uptime?)

Hi!


Well, got the problem that I am stress-testing some embedded devices
(console servers) for stability. Unfortunately, they crash somehow, and I
need to determine that they have crashed. The reboot time is quite quick, so
that even a check_ping that is scheduled once per minute sometimes cannot
catch them reliably.

My thoughts were:

1) put a script onto that device (embedded linux with ssh access and a
flashdisk) that sends email once the thing reboots

2) do it via nagios, perhaps checking the uptime via SNMP.

Has anyone written a check for this yet?

3) in the contrib dir is a check_uptime.c, that obviously needs
self-compiling the hard way, at least in my FreeBSD box the contrib dir
isn't being compiled automagically.

Versions of the Software:
# pkg_info |grep nagios
nagios-1.2          Extremely powerful network monitoring system
nagios-plugins-1.3.1_1 Plugins for nagios


Any suggestions?

TIA
Olaf
