How to configure Nagios ?

First of all, copy the checkglances.py file to your Nagios plugin folder.

Then enter the new section on your commands.cfg file:

define command{
    command_name checkglances
    command_line $USER1$/checkglances.py -H $HOSTADDRESS$ -s $ARG1$ -w $ARG2$ -c $ARG3$
}

define command{
    command_name checkglanceswithparam
    command_line $USER1$/checkglances.py -H $HOSTADDRESS$ -s $ARG1$ -e $ARG2$-w $ARG3$ -c $ARG4$
}

Configure a new service for your host (where Glances server is up and running):

define service {
    use generic-service
    host_name myhost
    service_description CPU
    check_command checkglances!cpu!70!90
}

define service {
    use generic-service
    host_name myhost
    service_description LOAD
    check_command checkglances!load!1!5
}

define service {
    use generic-service
    host_name myhost
    service_description MEM
    check_command checkglances!mem!70!90
}

define service {
    use generic-service
    host_name myhost
    service_description SWAP
    check_command checkglances!swap!70!90
}

define service {
    use generic-service
    host_name myhost
    service_description PROCESS
    check_command checkglances!process!30!100
}

define service {
    use generic-service
    host_name myhost
    service_description NETWORK eth0
    check_command checkglanceswithparam!net!eth0!7500000!10000000
}

define service {
    use generic-service
    host_name myhost
    service_description FILESYSTEM /
    check_command checkglanceswithparam!fs!/!70!90
}
