Re: [Nagios-users] How to get reboot messages
Sample command and uptime service is below. I have taken it from
objects.cache to show all the details. Note that is is volatile and only
alerts on warnings:-
|define command {
| command_namecheck_snmp_uptime
| command_line$USER1$/check_snmp -H $HOSTADDRESS$ -C $ARG1$ -o
1.3.6.1.2.1.1.3.0 -w 42000: -t 45
| }
|define service {
| host_name xxx
| service_description uptime
| check_period24x7
| check_command check_snmp_uptime!readcommunity
| contact_groups xxx
| notification_period 24x7
| initial_state o
| check_interval 5.00
| retry_interval 5.00
| max_check_attempts 1
| is_volatile 1
| parallelize_check 1
| active_checks_enabled 1
| passive_checks_enabled 1
| obsess_over_service 1
| event_handler_enabled 1
| low_flap_threshold 0.00
| high_flap_threshold 0.00
| flap_detection_enabled 1
| flap_detection_options o,w,u,c
| freshness_threshold 0
| check_freshness 0
| notification_optionsw
| notifications_enabled 1
| notification_interval 0.00
| first_notification_delay0.00
| stalking_optionsn
| process_perf_data 1
| failure_prediction_enabled 1
| retain_status_information 1
| retain_nonstatus_information1
| }
This config will occasionally give two successive warnings for one reboot,
which I intend to adjust in due course.
Hope this helps.
Best wishes,
Matthew

Re: [Nagios-users] How to get reboot messages
Here, we do this by checking the uptime of the host/device.For switches etc, this is in the SNMP counter. For windows hosts, it is via check_nt and the UPTIME object. For unix, you just create an appropriate script to run via nrpe. We then do a critical if uptime < 10min. Since hosts are checked every 5min at most then even if the hosts reboots quickly, this will alert. A scheduled outage is OK because the scheduled downtime extends 10min after the reboot. Steve I have a bunch of devices which alert me fine up/down, but I'm looking to find how to get messages when they reboot.

Re: [Nagios-users] How to get reboot messages
Thanks for all the replies, these would be Windows servers, Cisco/Juniper devices and Checkpoint boxes running mainly on SPLAT (linux) I prefer to do this with SNMP, as that's how I have done it on Solarwinds. I will be trying the SNMP_uptime command and report my results.

Re: [Nagios-users] How to get reboot messages
if you're trying to check windows boxes, I wouldn't use this snmp value because
I don't think it's set reliably. I've been using "check_nt -v UPTIME" for
those (but i still think it resets correctly at reboot).
Also, it may not say "0 days" (so you could look to see if "days" doesn't show
up); it may just give a time such as the following:
libexec # snmpget -v1 -c hrSystemUptime.0
HOST-RESOURCES-MIB::hrSystemUptime.0 = Timeticks: (8082663) 22:27:06.63
you'll have to play around w/ it, I guess (sorry for the top-posting).

hi,
One simple idea is to use the Uptime number from SNMP ("hrSystemUptime.0"),
and if that ever says "0 days" then you get an alert. I have a script that
does a little more than this, but that's the basic idea.
you should be able to do this with check_snmp (or a quick perl script that uses
snmpget and does regular expression matches).

Re: [Nagios-users] How to get reboot messages
We have our site-specific init script do this on Linux and Solaris. We also dump the users from last into the mail just in case a user rebooted a lab machine. The general algorithm is: -build the input to /usr/lib/sendmail in some file -mail it with `cat $file | /usr/lib/sendmail -oi $emailAddress` -if shutting down, wait 10 seconds (this was for older Solaris, may not be needed) Make it run last on boots and first on shutdowns and you should be good.
