Nagios – Example using check_icmp

Linux Nagios and NagiosXI

This is what would be needed in your hosts configuration to monitor using check_icmp rather than check_ping.

define service{

use                     generic-service ; Inherit values from a template

host_name               SWITCH    ; The name of the host the service is associated with

service_description     PING            ; The service description

check_command           check_icmp!40.0,10%!100.0,40%  ; The command used to monitor the service

normal_check_interval   5               ; Check the service every 5 minutes under normal conditions

retry_check_interval    1               ; Re-check the service every minute until its final/hard state is determined

}

This is what would be needed in the commands.cfg

# 'check-host-alive' command definition

define command{

command_name    check_icmp

command_line    $USER1$/check_icmp -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 2

}

This makes the assumption its going to do two pings, otherwise turn “-p 2” into $ARG3$ instead!
