Random Notes ill clean up later =)

This is a list of random notes i am using whilst deploying Nagios in a customer environment, I will clean these up in to a bit of a pholisy later =)

Check your config

before reloading its all ways a good idea to check your config

[Nagios base directory]/bin/nagios -v [Nagios base directory]/etc/nagios.cfg

eg

/opt/nagios/bin/nagios -v /opt/nagios/etc/nagios.cfg

Define a new service check for a group

this will add a new service check to all hosts in the solaris host group

define service {
        service_description     if_config
        display_name            if Config
        check_command           check_nrpe!check_ifcfg
        use                     generic-service
        hostgroup_name          solaris
}
