How will this help if one has 40 servers with each machine running NRPE? And where one wants each service on a machine being dependent on the NRPE instance of that machine only? It might work but you do not explain why it might work which I think would be vital information in this regard. And putting a dependency on someone elses NRPE server without knowing the person would not be a wise move in my view.

Hi its pretty simple solution without perl script. create a service called NRPE and enter the following check_command command_name nrpe_version command_line ./check_nrpe -H 212.150.36.20 when running this command against NRPE daemon you should get response "NRPE v2.0" now create your dependencies that this NRPE is the master server and the other dependent on it.

[Nagios-users] Notification commands
Hi All: Does anyone have any thoughts on notification best practices? I just wrote a little shell script to use heredocs to send mail. This seems preferable to the cookbook notifications, as it makes the message body a lot more intuitive (you can format the message visually). There's a simple caveat, the environmental variables that the shell sees are all prepended with "NAGIOS_". Looking at this, I added HTML email (multi-part alternative, easy enough). I know there's a script floating around Nagios Exchange to do this, but it did not work for me (I think it was built around an older version of nagios and macros may have changed). Of all this brings up a few questions I'd like to bounce off the mailing list. 1) Is there a compelling reason to stick with the one-line sendmail/printf notifications? I can't think of any (they already shell out, so the approaches seem functionally very close). 2) Would it make sense to build a smarter version. The first idea that occurs to me is to build it to recognize HOST vs SERVICE messages transparently. Thinking about this some more, and this seems like a fairly clean way to build "business logic" into the notifications (i.e., indicating specialized escalation information for certain cases). 3) Is anyone else interested in posting a version of this to the Nagios Exchange?

[Nagios-users] Service Dependencies - refer to self
Is there any way to make a service dependency refer to the service's own
host?
For example:
I have a list of services that perform basic health checking
(disk-space, swap-space, load, uptime etc) across all servers defined in
Nagios.
There is also a service on every server that checks that NRPE is running.
What I'd like to do is create a service dependency so that all the basic
health checks only get checked/notified if NRPE is running.
However, I cannot seem to create a dependency that refers to it's own host.
E.g.
define servicedependency {
hostgroup_nameall_servers
service_descriptionRemote Monitoring Agent
dependent_hostgroup_nameall_servers
dependent_service_descriptionDisk Space (OS)
inherits_parent0
execution_failure_criteriac
notification_failure_criteriaw,u,c,p
}
What this does, and I understand why, is that one server's "Disk Space
(OS)" service depends on every other server's "Remote Monitoring Agent",
instead of just it's own.
I'd need something like:
define servicedependency {
host_name_self
service_descriptionRemote Monitoring Agent
dependent_host_name_self
dependent_service_descriptionDisk Space (OS)
inherits_parent0
execution_failure_criteriac
notification_failure_criteriaw,u,c,p
}
So the service "Disk Space (OS)" is dependent on the "Remote Monitoring
Agent" on that same server.
The only way forward I can see for now is creating a service dependency
for every host, for every health check service (which for me means
upwards of 40 dependencies.)
I hope this is a good enough explanation of what I'm trying to do - can
this be done?
Thanks
Andy.

[Nagios-users] servicegroup_name in dependencies
Can anyone see a problem with this service dependency setup? Nagios
complains with a "NULL service description/host name in service
dependency definition" message with this configuration, but I cannot see
anything wrong myself.
According to the manual:
--- start man quote ---
All Services In Multiple Servicegroups: If you want to create service
dependencies for all services
that belong in one or more servicegroups, you can do use the
servicegroup_name and/or dependent_
servicegroup_name directive as follows:
define servicedependency{
servicegroup_name SERVICEGROUP1,SERVICEGROUP2,...,SERVICEGROUPN
dependent_servicegroup_name SERVICEGROUP3,SERVICEGROUP4,...SERVICEGROUPN
other escalation directives ...
}
--- end man quote ---
I cannot get this to work under Nagios 2.7.
In my setup, I have a group called "aseu_web_servers." Every host in
that group (currently only one) has a service called "Web Service"
which, using NRPE, checks that the local web server is running.
I then have a list of 13 websites assigned to a service group called
"web_sites".
What I'm trying to do is setup a dependency on every website, with the
"Web Service" on the host being the master service, so if the web server
dies, I don't get a notification for every website that fails.
With the above manual excerpt, I figured the following would work:
define servicedependency {
hostgroup_nameaseu_web_servers
service_descriptionWeb Service
dependent_hostgroup_nameaseu_web_servers
dependent_servicegroup_nameweb_sites
inherits_parent0
execution_failure_criteriac
notification_failure_criteriaw,u,c,p
}
Config check fails with: "NULL service description/host name in service
dependency definition"
If I change "dependent_servicegroup_name" to
"dependent_service_description" and put a single website in, instead of
the "web_sites" group, it works, as follows:
define servicedependency {
hostgroup_nameaseu_web_servers
service_descriptionWeb Service
dependent_hostgroup_nameaseu_web_servers
dependent_service_description Website: www.andyshellam.eu
inherits_parent0
execution_failure_criteriac
notification_failure_criteriaw,u,c,p
}
Config check results in "Total Warnings: 0; Total Errors: 0"
Even if I set a specific host name instead of a host group, it still
complains whenever the "dependent_servicegroup_name" option is used.
This means I'll have to add in a service dependency for every website.
I cannot use a wildcard in the "dependent_service_description" because
there are other services on those servers that don't have a dependency
on the web server. If I add a new website, all I want to have to do is
add it into the "web_sites" group and have everything else taken care
of, which the manual says you can by using the
"dependent_servicegroup_name" directive.
Is this a bug in Nagios, or can anyone tell me I'm missing something silly?
Thanks
Andy.
