Of course PNP should be easily accessible. You do not want to search long for the right graph.

Nagios itself features external URLs using so called extended info configs. Due to changes between Nagios 2.x and Nagios 3.x both versions are described.

With Nagios 2.x the integration of external URLs into the nagios web interface is made using Extended Info Objects for <a href="http://nagios.sourceforge.net/docs/2_0/xodtemplate.html#serviceextinfo" class="urlextern" title="http://nagios.sourceforge.net/docs/2_0/xodtemplate.html#serviceextinfo" rel="nofollow">services</a>. For PNP we use the directive action_url to call the PNP web frontend with the appropriate options.

||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
define serviceextinfo {
|
||
|
|
host_name localhost
|
||
|
|
service_description load
|
||
|
|
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
|

|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
You have to specify an additional Extended Info Definition for every service.

Since nagios 3.0 the action_url-directive has be moved to the <a href="http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#host" class="urlextern" title="http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#host" rel="nofollow">host</a> or <a href="http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#service" class="urlextern" title="http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#service" rel="nofollow">service</a> definition. This way the definition of URLs to the PNP-interface has been simplified. The <a href="http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#serviceextinfo" class="urlextern" title="http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#serviceextinfo" rel="nofollow">serviceextinfo</a> and <a href="http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#hostextinfo" class="urlextern" title="http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#hostextinfo" rel="nofollow">hostextinfo</a> definitions are deprecated.

First two nagios templates are defined. If you used the Nagios <a href="http://nagios.sourceforge.net/docs/3_0/quickstart.html" class="urlextern" title="http://nagios.sourceforge.net/docs/3_0/quickstart.html" rel="nofollow">quickstart installation guides</a> you can append these lines to templates.cfg:
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
define host {
|
||
|
|
name host-pnp
|
||
|
|
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_
|
||
|
|
register 0
|
||
|
|
}
|
||
|
|
|
||
|
|
define service {
|
||
|
|
name srv-pnp
|
||
|
|
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
|
||
|
|
register 0
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
These two templates can now be included via “use srv-pnp” or “use host-pnp” for services and hosts respectively. If you used the quickstart installation guide you might for example edit the file localhost.cfg and add the template to the host or service definition as follows:
|
||
|
|
</p>
|
||
|
|
<pre class="code">define host{
|
||
|
|
use linux-server,host-pnp ; Name of host templates to use
|
||
|
|
; This host definition will inherit all variables that are defined
|
||
|
|
; in (or inherited by) the linux-server host template definition.
|
||
|
|
host_name localhost
|
||
|
|
alias localhost
|
||
|
|
address 127.0.0.1
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
<pre class="code">define service{
|
||
|
|
use local-service,srv-pnp ; Name of service template to use
|
||
|
|
host_name localhost
|
||
|
|
service_description PING
|
||
|
|
check_command check_ping!100.0,20%!500.0,60%
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
|
||
|
|
The links to the correct URLs are created automagically.<br/>
|
||
|
|
<br/>
|

|
|
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
<strong>Tips</strong>: if you want to open the PNP window in your <em>main</em> frame (on the right of the menu) instead of a new page, just set <code>action_url_target=main</code> in your nagios cgi.cfg

You can integrate PNP into Nagios in a way that you have current graphs without clicking any icons. This can be accomplished using the <a href="http://nagios.sourceforge.net/docs/3_0/cgiincludes.html" class="urlextern" title="http://nagios.sourceforge.net/docs/3_0/cgiincludes.html" rel="nofollow">CGI Includes</a> which allow us to include JavaScript code in the status detail view ( status.cgi ).
