[Nagios-users] notifications not being sent on host down/unreachable
I have a nagios setup consisting of 2 distributed servers and one master
using nsca. I'm having an issue where notifications aren't being sent for
hosts going down or becoming unreachable but I see them in that state in the
GUI and the logs. If a service check fails the notification is sent fine but
if the whole box dies I'm never seeing a host down/unreachable alert. In
fact there is no notification listed in the notification history so it seems
to be a config issue. But I've looked through all of the configs multiple
times and just can't figure this out.
My host, service and contacts are defined with the following templates:
define host{
namestandard-host
max_check_attempts 3
check_interval 15
retry_interval 5
check_command check-host-alive
check_period24x7
notifications_enabled 1
retain_status_information 1
retain_nonstatus_information1
contactsops
notification_interval 15
notification_period 24x7
check_freshness 1
freshness_threshold 300
register0
}
define service{
namestandard-service
max_check_attempts 3
check_interval 5
retry_interval 3
check_period24x7
notification_interval 10
notification_period 24x7
notification_optionsu,c,r
contactsops
register0
check_freshness 1
freshness_threshold 300
}
define contact{
namestandard-contact
host_notifications_enabled 1
service_notifications_enabled 1
host_notification_period24x7
service_notification_period 24x7
host_notification_options d,u,r
service_notification_optionsc,u,r
host_notification_commands host-notify-by-email
service_notification_commands notify-by-email-verbose
register0
}

Hello,
This is just a template and not a complete host definition. In fact,
they were all just templates and missing critical pieces of
information or may have parts that are overridden in the full
definition. You should post the entire definition for the host,
contact group and contact as found in objects.cache. At first glance,
you don't specify any notification_options for the host. With
Nagios-3, this will mean that all states will result in a notification
but under 2.x I believe that behavior is different. I'd go ahead and
specify the specific states to you want to receive notifications for.

Re: [Nagios-users] notifications not being sent on host down/unreachable
I included the template because the actual host definitions only include the
server specific information. I'm not overriding anything. For example...
define host{
use standard-host
host_name server1
hostgroups +servers
alias server1
address server1.domain.com
}
The same goes for contacts everything else.

Re: [Nagios-users] notifications not being sent on host down/unreachable
So this is working now but I'm not sure why. I deleted the objects.cache
file and restarted and got a host down alert as soon as nagios came up.
On a whim I deleted the cache file and restarted nagios and it sent out a
host down alert. I didn't change anything else.

This tells me that nagios wasn't running with the configuration you thought it was (unless you also deleted status.dat, which may have settings overrides your object definitions). Seeing what was in objects.cache (and status.dat) might have explained the issue.

We're not mind readers and when you provide something that is incomplete, with no comment that it's known incomplete and why, we have to assume you don't know what you gave us. ;) IMHO, you (as in anyone reporting problems) should provide *all* related information for any problem regardless of what bits you think are needed. Usually the problem is not in what you know you need, but in what you don't know you need. =) -- Marc -- Come build with us!
