Define pnp4nagios host and service definitions
Pnp4nagios can be integrated in to Nagios using the action_url directive in host and service definitions to add an icon / link to graphs.
The first step to integrate pnp4nagios with the Nagios web interface is to define host and service definitions by performing the following steps:
- Logon to the Raspberry Pi and execute the following command to become root:
sudo -i
- Backup the existing /usr/local/nagios/etc/objects/template.cfg file (Optional step)
cp /usr/local/nagios/etc/objects/templates.cfg /usr/local/nagios/etc/objects/templates.cfg-beforepnp4nagios
- Next edit /usr/local/nagios/etc/objects/templates.cfg using the editor of your choice
- Go to the end of the file and add the host and services definitions below:
define host {
name host-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=HOST
register 0
}
define service {
name service-pnp
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
register 0
}
Update the Nagios generic definitions
- Next locate the generic-host definition and add in the line shown below in bold:
define host{
name generic-host ; The name of this host template
use host-pnp
- FInally locate the generic-service definition and add in the line shown below in bold:
define service{
name generic-service ; The 'name' of this service template
use service-pnp
- Save and exit the file
- Following the modifications to the templates.cfg file Nagios needs to be restarted by executing the following command:
systemctl restart nagios
PHP 7 Modification
Following the installation and configuration of pnp4nagios I encountered the error shown in the screen shot below:
A quick google turned up the following article https://github.com/lingej/pnp4nagios/issues/148 which gave the solution below for me as my Pi is running PHP 7:
- Edit the /usr/local/pnp4nagios/share/application/models/data.php file
- Go to line 979 and change if(sizeof($pages) > 0 ){ to if(is_arrary($pages) && sizeof($pages) > 0 ){
- Save and exit the file
