Hey! I tried as you suggested. I checked the curl on command line and then it worked perfectly fine. Then I added that command in /usr/local/nagios/etc/objects/command.cfg file like below,
Code: Select all
# 'notify-service-by-http' command definition
define command{
command_name notify-service-by-http
command_line /usr/bin/curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X POST -d '{"notification":{"host":$HOSTADDRESS$, "service":$SERVICEDISPLAYNAME$, "state":$SERVICESTATE$, "host-state-type":$SERVICESTATETYPE$, "notification-type":$NOTIFICATIONTYPE$, "attempts":$SERVICEATTEMPT$, "max-attempts":$MAXSERVICEATTEMPTS$, "time":$TIME$}}' http://192.168.56.113:9090/things > /tmp/notification.log
}
For testing, i increased the load and below message displays but no notification is received. The web interface displays the below message,
Code: Select all
http admin CRITICAL 03-19-2016 00:50:17 0d 0h 9m 0s 3/3 CHECK_NRPE: Socket timeout after 10 seconds.
My contact.cfg
Code: Select all
define contact{
contact_name saas-app ; Short name of user
use generic-contact ; Inherit default values from generic-contact template (defined above)
alias scaling as a service ; Full name of user

# host_notification_options w,c,r
# host_notification_commands notify-host-by-http
service_notification_commands notify-service-by-http
# register 0
}
define contactgroup{
contactgroup_name saas
alias scaling as a service notifying group

}
object.cfg
Code: Select all

}
define service {

Hi @rkennedy, I tried as you told but unable to receive any notification at my service side. I have ensured thay my service is up and listening for the request. I checked the curl in command line before puting below code in /use/local/nagios/etc/objects/command.cfg.
Code: Select all
# 'notify-service-by-http' command definition
define command{
command_name notify-service-by-http
command_line /usr/bin/curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X POST -d '{"notification":{"host":$HOSTADDRESS$, "service":$SERVICEDISPLAYNAME$, "state":$SERVICESTATE$, "host-state-type":$SERVICESTATETYPE$, "notification-type":$NOTIFICATIONTYPE$, "attempts":$SERVICEATTEMPT$, "max-attempts":$MAXSERVICEATTEMPTS$, "time":$TIME$}}' http://192.168.56.113:9090/things > /tmp/notification.log
}
For testing, I increased load n my service and got below message on web interface. but no notification had been sent.
Code: Select all
http admin CRITICAL 03-19-2016 00:50:17 0d 0h 9m 0s 3/3 CHECK_NRPE: Socket timeout after 10 seconds.
For you convenience I am also adding code for my contact.cfg and object.cfg respectively.
/usr/local/nagios/etc/objects/contact.cfg
Code: Select all
define contact{
contact_name saas-app ; Short name of user
use generic-contact ; Inherit default values from generic-contact template (defined above)
alias scaling as a service ; Full name of user
service_notification_options w,c,r
# host_notification_options w,c,r
# host_notification_commands notify-host-by-http
service_notification_commands notify-service-by-http
# register 0
}
define contactgroup{
contactgroup_name saas
alias scaling as a service notifying group
members saas-app
}
-> /usr/local/nagios/etc/objects/my_object.cfg
Code: Select all
define host{
host_name ubuntu-VirtualBox
address 192.168.56.113
notifications_enabled 1 ; Host notifications are enabled
event_handler_enabled 0 ; Host event handler is enabled
flap_detection_enabled 0 ; Flap detection is enabled
failure_prediction_enabled 1 ; Failure prediction is enabled
process_perf_data 1 ; Process performance data
retain_status_information 1 ; Retain status information across program restarts
retain_nonstatus_information 1 ; Retain non-status information across program restarts
check_command check-host-alive
max_check_attempts 3 ; recheck the service before notifying the contact
retry_check_interval 60 ; recheck intervals
notification_interval 0
# notification_options w,c,r
contact_groups saas
register 1 ; DONT REGISTER THIS DEFINITION – ITS NOT A REAL HOST, JUST A TEMPLATE!
}
define service {
host_name ubuntu-VirtualBox
service_description keystone http admin
check_command check_nrpe!check_keystone_http_admin
use generic-service
notification_interval 0 ; set > 0 if you want to be renotified
}

I do this to integrate servicedeskplus and nagios, on alrert my script posts data to the HTTP api of servicedeskplus
one gotcha I found was that nagios was creating tickets every time it ran the notify script so I added a simple mysql datbase to keep track of the incident number in Nagios and the incident number in service desk plus, that way if the same issue was being notified a 2nd or subsequent times it performed a different action, instead of creating a new ticket it adds a note to the existing ticket to let you know that the issue is still there
if that sort of thing would be helpful for you I can share you my script, its not well written

Well! i don't know the reason of not receiving notifications. If you think your solution will work in my case then please share your script. Thanks

Is there a reason you have notification_options commented out for your host? Also, you have no notification_options defined in your service definition.
Take a look at this page for more information on notification_options,
