Good morning everyone!
We have run into an interesting situation trying to set up some service
escalations, and I BELIEVE the attached patch is an appropriate general
fix, but would appreciate any comments or additional thoughts. First,
an explanation of what I'm trying to do:
I would like to have service escalations defined for all services except
"NTP Time Offset" on all hosts not in the "gtpods" hostgroup. To
accomplish this, I had defined my service escalation as follows:
define serviceescalation {
host_name *
hostgroup_name !gtpods
service_description *,!NTP Time Offset
first_notification 1
last_notification 5
notification_interval 10
contact_groups admins,oncall
}
Under stock Nagios 3.2.0, this fails with the following error, because
not all hosts have an "NTP Time Offset" service defined:
Error: Could not find a service matching host name 'servXX' and
description 'NTP Time Offset' (config file
'/usr/local/nagios-3.2.0/etc/objects/escalations.cfg', starting on line 62)
Error: Could not expand services specified in service escalation (config
file '/usr/local/nagios-3.2.0/etc/objects/escalations.cfg', starting on
line 62)
Error processing object config files!
As the code stands today, when expanding service escalations, if a
negated service is not attached to the host in question, it returns this
error. But in my opinion, a negated service that would wind up on the
reject list can just be silently ignored when it doesn't exist on a
host, because the behavior is identical, and in fact more intuitive to
the configuration writer.
The attached patch simply adds a check of reject_item to two
conditionals within xodtemplate_expand_services, which I believe should
make this work in the way that I perceive as intuitive without
compromising any other configuration scenarios. I have tested my
specific scenario and the configuration is built as I would expect and
intend. I'm happy to receive any feedback, thoughts on better ways to
accomplish this, etc!
Thanks,
Tim Wilde
