Configuration

PNP Configuration

The base URL for PNP (e.g. /pnp4nagios) must be accessible on the webserver.

There is an open issue for forwarding the Icinga Web 2 auth session to PNP.

Module Configuration

Navigate to Modules - PNP - Config and specify the settings.

FAQ

Duplicated Graphs in Detail View

There is a problem with config.php and config_local.php in PNP (discussion here).

Remove the duplicated views in one of them, e.g. in config_local.php:

- $views[] = array('title' =&gt; '4 Hours',   'start' =&gt; (60*60*4) ); 
- $views[] = array('title' =&gt; '25 Hours',  'start' =&gt; (60*60*25) ); 
- $views[] = array('title' =&gt; 'One Week',  'start' =&gt; (60*60*25*7) ); 
- $views[] = array('title' =&gt; 'One Month', 'start' =&gt; (60*60*24*32) ); 
- $views[] = array('title' =&gt; 'One Year',  'start' =&gt; (60*60*24*380) );

The related issue can be found here.

Preview Graphs Missing in Detail View

First off, the module needs to read the local PNP configuration files and as such you need to ensure that the path can be read by the web server user. SELinux may prevent this too next to wrong permissions or wrong paths. This path defaults to /etc/pnp4nagios and requires adjustments for your own needs. If the module is not able to read the configuration, an error will be logged to the debug log and no graph will be rendered.

Also ensure that the user who is not seeing the graphs actually has the permission to view the PNP module. Navigate into your roles configuration and verify that.

PNP stores meta information in an XML file next to the actual RRD file. If this file is missing in your RRD data store, the module won't render graphs. Verify that PNP and NPCD are running and troubleshoot why metrics are not updated. The debug level helps here.

Last but not least, if there are no graphs available, the detail view won't show any graphs. You can verify that by opening the native PNP interface and search for the corresponding host or service.
