Nagios Support Forum

Hi Guys,

I am trying to get notifications as soon as a service goes down but its not working.
I get emails after the service has been down for a while and then don't get notified when it comes back up.
How can I do this?

I have attached three files.
The nsclient.cfg is where i have put the commands for the nsclient checks.
I have added in the check_nrpe into the bottom of the command.cfg.
Templates is what my hosts / services use.

I could only add three files so , please find a copy of my contact.cfg inline
#contacts.cfg
define contact{
contact_name nagiosadmin ; Short name of user
use generic-contact ; Inherit default values from generic-contact template (defined above)
alias Nagios Admin ; Full name of user
service_notification_period 24x7
host_notification_period 24x7
service_notification_options u,r,c
host_notification_options d,r,u
service_notification_commands notify-service-by-email
host_notification_commands notify-host-by-email
email [email protected] ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******
}

The server configuration is below

I'm not sure I understand what you mean by "as soon as it goes down" but if you mean you want notifications at the first sign of trouble, then you need to change "max_check_attempts" from 3 to 1 in your template.

Precisely, if you want more specific help you will need to share your templates that are in use.

Edit: Ah, there it is, thank you.

Sorry guys,

The attachments and incline snips are what I am using.

And yes I was meaning as soon as the service is in trouble, I will try setting the max_check_attempts to 1

Yeah, give it a shot and let us know, that is the directive you will want to change. Just make sure you do it on the object itself, or the template, if you leave the object at 3, instead of 1, but change the template, it won't be inherited, as objects over-ride templates when the same directive is defined.
