Hi and welcome to Nagios,
you have to define a check command in your services.cfg and in your
checkcommands.cfg.
#checkcommands.cfg
# 'check_ping' command definition
define command{
command_name check_ping
command_line /usr/local/nagios/libexec/check_ping -H $HOSTADDRESS$ -w 10:20% -c 60:100%
}
#services.cfg
#'TEST' host definitions
define service{
host_name TEST
service_description PING
is_volatile 0
check_period 24x7
check_command check_ping
max_check_attempts 4
notification_interval 3600
notification_period 24x7
obsess_over_service 1
notifications_enabled 1
notification_options r,c
normal_check_interval 600
retry_check_interval 1
contact_groups admin
}
just have a look at the realy good documentation!
The checkcommand 'check_ping' fires up a plugin stored in
/usr/local/nagios/libexec/check_plugin, the special about this
plugins is, that they returns values between -1 and 2 (i think) which
stands for UNKNOWN, CRITICAL, WARNING and OK. These Return-Codes are
"readable" by the Nagios Process.
Hope this helps a little.
Best regards,
Hendrik
