Current event and notifications

Nagios
1

Hi.

I needed to monitor a temperature monitor on my network. I wrote my own shell script and put it in the check commands folder as normal.

#!/bin/sh

origtemp=$(/sbin/gettemp)
temp=$(/sbin/gettemp | sed 's/\..*//')

if  $temp -gt "100" ]; then

echo "Critcal Temperature: $origtemp"
exit 2

else

echo "Temperature OK: $origtemp"
exit 0

fi

However while monitoring the script in nagios I never get notifications. However I have it setup just like every other single service that we monitor. From what I know about writing scripts it should get all its info from exit codes. Which is what I used in my script.

I also noticed that current attempt never changes from 1/2 and is always in HARD state.

Current Attempt: 1/2 (HARD state)

Here is my config:

define service{
use service
hostgroup_name server_room_monitor
service_description ENVIROMUX-TEMP
check_command check_enviromux_temp
notifications_enabled 1
max_check_attempts 2
is_volatile 1
notification_interval 5
}

define serviceescalation{
host_name server-room-monitor
hostgroup_name server_room_monitor
service_description ENVIROMUX-TEMP
contacts nagiosadmin

contact_groups admin

    first_notification      2
    last_notification       0
    notification_interval   5
    escalation_period       24x7
    escalation_options      w,u,c,r
    }

What is wrong why will it not give me any emails when in critical state?

Please help.

Here is what is in the rest of the services area:

Generic service template

}

Have you seen it go from OK to Critical? Notifications will only be triggered initially by a state change.
