[Nagios-users] Host-based service check period

[Francis Dube]

Hi everyone,

I'm using Nagios to monitor many hosts with services running at
different time. Each host is connected to a Plasma TV and display
publicity on it, but the all are installed in different public area with
different working hours.

Ex :
Host #1 is in a restaurant, so the services are running from 6:00 to 21:00.
Host #2 is in a bar, so the services are running from 12:00 to 3:00.
Host #3 is in a mall, so the services are running from 9:00 to 17:00 on
week days.

To save power, we turn off the display during the non-working hours, but
we need the Nagios check to stop at the same time. The check_period
instruction in the host definition only affect the check-host-alive
command and not the services check. I've read all i've found about the
timeperiod and such, but i cant find a way to do host-based service
check period. I would like to create a timeperiod for each host and that
all the check for this host (service and host-alive) stop/start
according to that timeperiod. Anybody knows a way to do this ?

Thanks for your time !

Host and services have historically been separate entities for the
most part with no inheritance between them at all. With nagios-3,
there is some inheritance happening now between a service and it's
host but only for three variables (contact_groups,
notification_interval and notification_period: http://nagios.sourceforge.net/docs/3_0/objectinheritance.html#implied_inheritance)
. check_period isn't an inheritable property and the most direct way
to a solution is to simply specify the same check_period name for the
services that you are using for the host.

Yeah but if I specify the same check_period name for the service, I
have to define a service for every host (ex : a check_service_host1,
check_service_host2, and so on..) because the services running on
each hosts are running at different hours.

Correct. The possibility does exist that you've chosen a config
management scheme that doesn't meet your needs. Template shortcuts are
nice but you can lose a lot of flexibility.

I'll take a look at notification_period inheritance, it may be a
good work around too.

I agree, if you don't mind that the checks still happen.

Any thoughts on these errors? I'm stumped.

Checking services...

Error: Service check command 'check_ssh' specified in service 'SSH' for
host 'server1' not defined anywhere!
Error: Service check command 'check_ssh' specified in service 'SSH' for
host 'server2' not defined anywhere!

Services page looks like this..

define service{
use generic-service
hostgroup_name ssh_servers
service_description SSH
is_volatile 0
check_period 24x7
max_check_attempts 3
normal_check_interval 3
retry_check_interval 1
contact_groups admins
notification_interval 30
notification_period 24x7
notification_options w,u,c,r
check_command check_ssh
}

Thanks!

You need to define this command in your command.cfg file. A check_ssh=
=20
command usually looks like this :

# 'check_ssh' command definition
define command{
command_name check_ssh
command_line $USER1$/check_ssh -H $HOSTADDRESS$
}

Any ideas?

[sudo] password for user:

kill: 1: No such process


[ OK ]

Thanks!

Eliminate sudo as a culprit. Can you run it directly as root --

/etc/init.d/nagios2 start
or
/path/to/nagios/bin/nagios
or
/path/to/nagios/bin/nagios -v /path/to/nagios/etc/nagios.cfg
or
/path/to/nagios/bin/nagios -d /path/to/nagios/etc/nagios.cfg

Did you happen to mount the partition that the nagios binary lives in
with noexec?

What OS is this on?

Hi,

/etc/init.d/nagios2 script trying to kill something in "start" case. You
can check it by editing the /etc/init.d/nagios2 file content.

Where did you get a nagios2 binary? The Ubuntu repos? I've never seen
that before.
