Nagios Assignment - 4

To Be Performed:

1. On both the slaves run a CPU checking service
2. Reduce the check interval on slave2 to 1 minute since it’s a critical server

To create a service that checks CPU load, I copied the definition from localhost.cfg and modified it accordingly for my specific needs.

define service {
 
    use                     local-service  
    host_name               localhost
    service_description     Current Load
    check_command           check_local_load!5.0,4.0,3.0!10.0,6.0,4.0
}

For host1.cfg, I changed the host_name

define service {
 
    use                     local-service  
    host_name               my-linux-host1
    service_description     Current Load
    check_command           check_local_load!5.0,4.0,3.0!10.0,6.0,4.0
}

For host2.cfg, in addition to changing the host_name, I also added a check_interval parameter with a value of 1 to overwrite the default values.

define service {
 
    use                     local-service  
    host_name               my-linux-host2
    check_interval          1
    service_description     Current Load
    check_command           check_local_load!5.0,4.0,3.0!10.0,6.0,4.0
}

Restarted Nagios service

sudo systemctl restart nagios

Now, the ‘Current Load’ service appears as a monitored service for both my-linux-host1 and my-linux-host2 in the Nagios interface.
