Greetings all.
I need some help with the event handlers.
I am trying to have Nagios restart services on remote servers when it sees the service is down. I can do all the commands manually to restart the services. The problem seems to be in the event handler script.
Here is my service config:
# Service definition - test server
define service{
use eplus-service
event_handler_enabled 1 ; Service event handler is enabled
host_name test
service_description HTTP
event_handler remote-restart-httpd
contact_groups linux-admins
check_command check_http
notification_options c,r
is_volatile 0
check_period 24x7
max_check_attempts 3
normal_check_interval 3
retry_check_interval 1
notification_interval 120
notification_period workhours
}
Here is my remote-restart-httpd script:
#!/bin/sh
case "$1" in
OK)
;;
WARNING)
;;
UNKNOWN)
;;
CRITICAL)
# Is this a "soft" or a "hard" state?
case "$2" in
SOFT)
case "$3" in
3)
echo -n "Restarting HTTP service (3rd soft critical state)..."
# Call the init script to restart the HTTPD server
ssh $HOSTADDRESS$ sudo /etc/rc.d/init.d/httpd restart
;;
esac
;;
HARD)
echo -n "Restarting HTTP service..."
# Call the init script to restart the HTTPD server
ssh $HOSTADDRESS$ sudo /etc/rc.d/init.d/httpd restart
;;
esac
;;
esac
exit 0
I can run commands from the Nagios server as the Nagios user and they work.
ssh 172.31.1.34 sudo /etc/rc.d/init.d/httpd status
This will return my httpd server status.
Thanks for any help you can offer.
