Service Alerts and Notifications

[Andy Shellam (Mailing Lists)]

Thanks for the info Wes,

As it appears to work OK I'll try it out on my new box before it goes 
live, I was a bit cautious with all the warnings about un-tested 
consequences etc.
Can you not do your web request with the check_http plugin, or does it 
require something a bit more complicated?

Andy.
