Same here... we have a few machines that can reboot in less than 2
minutes and with Nagios only checking them every 5 minutes or so, some
reboots can slip through the cracks. We have an "uptime" test that is
critical at less than 30 minutes and warn at less than 60 seconds, plus
resolution notifications enabled. So if a machine panic reboots and
Nagios misses it, withing 5 minutes the uptime test will show uptime of
less than 30 minutes and send an alert.<br>

<pre wrap="">Hello everybody,
I'm new to the boards, so this topic might already be covered. But
I'm not exactly sure how to fully search the boards.
Issue at hand:
I have successfully setup Nagios 3 on Ubuntu 8.10. I have a few
test servers being monitored, but what I can't get working properly
are when the servers reboot. I'm looking for a way to monitor when
a server reboots or has an unexpected shutdown.
I've tried the host-is-alive and also the ping, but the server comes
up to fast. I've also tried just monitoring a service, such as the
NSClient++ but Nagios doesn't notify me right away once the server
reboots.
How is everybody monitoring server reboots. I've used Whats Up Gold
in the past, and it would notify me right away. There has to be a
way to monitor reboots and get a notification of that reboot. Many
people have suggested I use scripts, but I don't know how to write
scripts.

In past, we monitored "uptime < 5 min", there might be a contributed
script or plugin. I would look, but have spotty Internet right now.
