Re: [Nagios-users] Nagios Reboot Notification
One way to check on a system reboot I've used before is with NagEventLog. We use NagEventLog to look for certain errors posted to the system/app eventlogs. Note these are "passive" checks so how soon you get notified will depend on the configuration of said passive checks as well as Nagios config. NagEventLog is reasonably configurable to filter our or only look for specific events such as an "unexpected shutdown". -- Mat W. http://www.techadre.com Date: Thu, 11 Jun 2009 16:29:40 -0700 From: teckad...@gmail.com To: nagios-users@lists.sourceforge.net Subject: [Nagios-users] Nagios Reboot Notification Marc, I don't think this will work for me ...reason being Nagios will do its check, lets say every minute. If the server reboots unexpectedly and comes up in between that check period, Nagios will never see the reboot. I could be wrong, but is that not accurate? Other application will notify you as soon as the server shuts down or reboots. Is this because its being monitored differently or different checks are being executed. As a Nagios newb, it seems that Nagios has cycles of running checks that the user defines. But I would like to try you suggestion. Will I simply add the define command in the commands.cfg config file and then reference that with the check_command in the hosts.cfg file?

Hmm, a trap coming from the PSU (sudden current change), or switch (link going down then up) Most monitoring systems I've seen use uptime, keep a track of the last value, and the time it happened, then alert if that value resets to close to zero (or even if it returns outside of a predicted range). The reason you keep a track of the value is to avoid broken alerts when the snmp counter rolls over. http://www.bbc.co.uk/ This e-mail (and any attachments) is confidential and may contain personal views which are not the views of the BBC unless specifically stated.

Sure it will. uptime is a counter that increases from 0 to infinity (essentially) and resets on reboot. The snmp check I use says that if that counter is less than 50,000ms (~8.3 minutes), show a WARNING. If you check every minute, you'd see a WARNING status for 7 or 8 minutes, then a reset to OK. > Other application will notify you as soon as the server shuts down > or reboots.

Yes. This presumes that you've configured SNMP on the target device and set the read communities to match on both sides. -- Marc -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
Re: [Nagios-users] Nagios Reboot Notification
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. A.

I monitor uptime via snmp and throw a quick WARNING in the GUI if I
see it. You'll likely want to adjust the warning and add critical
thresholds if you want alerts --
define command {
command_name check_uptime
command_line $USER1$/check_snmp -H $HOSTADDRESS
$ -C -o 1.3.6.1.2.1.1.3.0 -l "Uptime" -u "Timeticks" -w
5:0
}
