Nagios

Debian

aptitude install nagios3 nagios-plugins nagios-nrpe-plugin nagios3-doc

Set domain if you have one (else leave default) and set login user and password (it should prompt your for both)

At the time I had to apply the fix that is here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=626462

General Ping Monitoring

You put a host config file in the host config directory and restart nagios. It will then pull the new host in.

/etc/nagios3/conf.d

Contains templates that you can pull into your host config files.

/etc/nagios3/conf.d

is also where you put your host config files.

• Example

define host{
        use                     generic-host            ; Name of host template to use
        host_name               HOSTNAME
        alias                   HOSTNAME
        address                 192.168.52.20
        }

Save that in

/etc/nagios3/conf.d

and

/etc/init.d/nagios3 restart

you should see it pop in
