fs_/usr service escalation issue

nunezric · Post by **nunezric** » Sat Feb 02, 2013 8:17 pm

Hi,

Our Nagios service escalation for fs_/usr service is not working. We believe it should be related to the “/” character.

mtl1log02 server belongs to “linux-servers” host group.

Parts of /etc/check_mk/main.mk:

all_hosts = [
(…)
"mtl1log02|linux|linux-servers",
(..)
]
(…)
host_groups = [
(…)
( 'linux-servers', [ 'linux-servers' ], ALL_HOSTS ),
(…)
]
(…)

I defined a service escalation for this host group (file /usr/local/nagios/etc/serviceescalations.cfg):

define serviceescalation {
hostgroup_name linux-servers
service_description adinfo,CPU load,fs_/,fs_/boot,fs_/tmp,fs_/usr,fs_/usr/export/home,fs_/var,Memory used,ypwhich
contacts service-now
first_notification 1
last_notification 1
notification_interval 1440
escalation_period 24x7
escalation_options c,
}

These services were added by hand as using the Nagios Core in order to define the escalation.

/usr/local/nagios/etc/services/adinfo.cfg
define service {
service_description adinfo
display_name adinfo
register 1
}

/usr/local/nagios/etc/services/fs_usr.cfg
define service {
service_description fs_/usr
register 1
}

The critical adinfo problem was escalated, but not the fs_/usr issue. We believe it should be related to the “/” character.

these don't appear to be complete definitions. In addition you should not edit the files directly in /usr/local/nagios/etc/services it is a bad idea. If you want to manually edit configuration items they should be placed in /usr/local/nagios/etc/static otherwise, all items should be managed through Configure -> CCM

Yes, I used Nagios CCM to define those services. I was just avoiding to copy/paste too much garbage. I'll do that now:

In /usr/local/nagios/etc/services we have chosen these two files for this issue:

adinfo.cfg:
###############################################################################
#
# Service configuration file
#
# Created by: Nagios QL Version 3.0.3
# Date: 2013-02-01 23:38:56
# Version: Nagios 3.x config file
#
# --- DO NOT EDIT THIS FILE BY HAND ---
# Nagios QL will overwite all manual settings during the next update
#
###############################################################################

define service {
service_description adinfo
display_name adinfo
register 1
}

###############################################################################
#
# Service configuration file
#
# END OF FILE
#
###############################################################################

fs_usr.cfg:
###############################################################################
#
# Service configuration file
#
# Created by: Nagios QL Version 3.0.3
# Date: 2013-02-01 23:38:56
# Version: Nagios 3.x config file
#
# --- DO NOT EDIT THIS FILE BY HAND ---
# Nagios QL will overwite all manual settings during the next update
#
###############################################################################

define service {
service_description fs_/usr
register 1
}

###############################################################################
#
# Service configuration file
#
# END OF FILE
#
###############################################################################

I do believe the issue is related to the character "/"

Are there specials configurations on your system, ie; is Gnome installed? Are you using a proxy? Are you using SSL? No, No, No

Neither of the services you defined have hosts or hostgroups associated with them. They also are missing check commands as well as other settings..

Every service must have a host or will not perform any checks..

Am I missing something in your configuration?

nunezric · Post by **nunezric** » Mon Feb 04, 2013 4:18 pm

You were right.

I've attached a zip file which has the actual /usr/local/nagios/etc/static/check_mk_objects.cfg file.

You will see that a lot of devices have these services.

I didn't realize you had items in the static directory for these services....

Let me re-look at the thread...

scottwilkerson · Post by **scottwilkerson** » Mon Feb 04, 2013 5:21 pm

Can you verify that EVERY host in linux-servers hostgroup has ALL of these services

Code: Select all

adinfo,CPU load,fs_/,fs_/boot,fs_/tmp,fs_/usr,fs_/usr/export/home,fs_/var,Memory used,ypwhich

nunezric · Post by **nunezric** » Tue Feb 05, 2013 9:22 am

Yes, every host which belongs to linux-servers has all of those services.

If not, Nagios CCM won't let me "Apply Configuration" when I was adding the service escalation.

Is Ricardo Nunez part of the admins contact group which is added as the contacts for these checks?

nunezric · Post by **nunezric** » Wed Feb 06, 2013 4:52 pm

Attaching a ZIP file which has:

/usr/local/nagios/etc/contactgroups.cfg
/usr/local/nagios/etc/contacts.cfg

By the way, "Ricardo Nunez" does receive the e-mails regarding fs_/usr service, the problem is that is doesn't escalate. The alerts related to "adinfo", for example, do escalate. That's the issue I'm having.

In other words, "Ricardo Nunez" always receives the alerts, but the “service-now” contact does receive the adinfo alerts but NOT the fs_/usr alerts.

Attaching a another ZIP file which has:

/usr/local/nagios/etc/serviceescalations.cfg
