== Configuration of PNP for Nagios ==

=== Configuring Apache2 ===

The pnp graphs can be viewed with a webinterface. If the webserver
is not already running, start it with the following two commands:

insserv apache2
	rcapache2 start

Per default, only connects from localhost are allowed. Adjust the configfile
'''/etc/apache2/conf.d/nagios-pnp.conf''' for your needs. And define the 
apache server flag '''PNP4NAGIOS''' in '''/etc/sysconfig/apache2''' in the 
following line:

APACHE_SERVER_FLAGS="PNP4NAGIOS"

If not already done for nagios, create a password file for apache and add an 
apache user named 'nagiosadmin' (or any other username you like):

touch /etc/nagios/htpasswd.users
	chown root:www /etc/nagios/htpasswd.users
	chmod 640 /etc/nagios/htpasswd.users
	htpasswd2 -s /etc/nagios/htpasswd.users nagiosadmin

You can also use an alternative htpasswd file to allow only a limited amount 
of people to view the pnp graphs.

Therefore you should point the 'AuthUserFile' value in 
'''/etc/apache2/conf.d/nagios-pnp.conf''' to the location of your htpasswd file.

=== Configuring Nagios ===

Your next step should now be to enable performance data
in your '''/etc/nagios/nagios.cfg''' with following option:

process_performance_data=1
and: 
     host_perfdata_command=process-host-perfdata
     service_perfdata_command=process-service-perfdata

In your commands.cfg you have to add a commands like this:

define command {
    command_name    process-service-perfdata
    command_line    $USER1$/process_perfdata.pl
 }

define command {
    command_name    process-host-perfdata
    command_line    $USER1$/process_perfdata.pl
 }

and after this set the service option:

process_perf_data 1

for each service that supports 'real' performance data
and finaly which you wants to see within PNP.

{{Info|With Nagios 3.x you can put "process_perf_data 1" in your service definition or template!}}

=== Including links in Nagios' Webfrontend ===

For integrating the URLs you could create "hostextinfo" or "serviceextinfo"
objects:

# For all hosts go to the overview page
 define hostextinfo {
    host_name   *
    action_url  /pnp/index.php?host=$HOSTNAME$
 }

# For one service
 define serviceextinfo {
    host_name       localhost
    service_description Ping
    action_url  /pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
 }

{{Info|With Nagios 3.x you can put "action_url" in your service definition or template!}}

== Enabling the Nagios-Perfdata-C-Daemon ==

Don't forget to enable the Nagios-Perfdata-C-Daemon with

insserv npcd
    rcnpcd start

at the end...

Have a lot of fun!
