Hello and thanks for your reply,

- Can we see the exact configuration?

Sure, which configuration would you require? Icinga/PNP/rrdcached/.. ? Which exact files?
As I stated in my original post, I used the supplied guide in order to get PNP up and running, so all configurations are identical to the ones there.

You said something about a services.conf where services exist which do not generate any perfdata and therefore rrd files.

"pnp only recieves performance data from services which are directly configured under the host, but not for services which were applied from services.conf ."

I was curious how they would look like.


Here's the service configuration, which was included in the .deb package from the repo (the only thing added is action_url):

It's still a sample config, and shall be revised/modified by your own strategy. Find more on best practices on the documentation on that: http://docs.icinga.org/icinga2/latest/doc/module/icinga2/toc#!/icinga2/latest/doc/module/icinga2/chapter/monitoring-basics#configuration-best-practice



apply Service "ping4" {
  import "generic-service"

  check_command = "ping4"
  vars.sla = "24x7"

  assign where "linux-servers" in host.groups
  assign where "windows-servers" in host.groups
  ignore where host.address == ""

  action_url = "/pnp4nagios/graph?host=$HOSTNAME$&srv=$SERVICEDESC$' class='tips' rel='/pnp4nagios/popup?host=$HOSTNAME$&srv=$SERVICEDESC$"
}


And here's a listing of the perfdata/localhost folder, so you could see other services are creating and populating rrd-files:

It doesn't make sense to debug three different locations for "no graph is shown"

* Verify which command is being executed given the configuration objects
* Validate the check plugin manually providing the correct performance data

Only if these points are done, step to npcd/process perfdata. And if their logs don't tell anything, dive into rrdtool.


- Verify that these check commands and plugins provide valid performance data.

"..even though I can see the performance data under "Service State Information" ". Here's what I see under the service ping4 as an example - Performance Data:pl=0%;5;15;0 rta=3.1999999999999999e-05s;0.1;0.2;0

Run the plugin manually as Icinga 2 would execute it, and post the entire output.




- Hard to tell with that little details you provided.

"Please let me know if you require any additional details from my end." :)

I'd remove the wiki guide, and move it to the documentation. I'm not very keen on a split mode between the wiki and the docs, as happened with 1.x. If you have anything to add to the docs, please send a patch to the issue - https://dev.icinga.org/issues/6858

Hello,

I set up the latest version (2.0.1) of Icinga2 on an Ubuntu 14.04 Machine with ClassicUI and pnp4nagios using the official repository. Everything seems to be working, including my integration with the ClassicUI, accept for one issue - pnp only recieves performance data from services which are directly configured under the host, but not for services which were applied from services.conf .

Can we see the exact configuration?



Example - With the supplied test configs, I can see graphs for services such as users, procs, and swap, but not for ping4 nor ping6, even though I can see the performance data under "Service State Information".
There are also no rrd files created for these services under /var/lib/pnp4nagios/perfdata/localhost

Verify that these check commands and plugins provide valid performance data.



Is it a current limitation/bug, or am I doing something wrong?

Hard to tell with that little details you provided.


Please let me know if you require any additional details from my end. I followed this guide in order to get pnp up and running:

Thanks in advance.
