When creating an alert for a NetPath Service - we can have the same service assigned to multiple probe (locations). Yet there's no way to get the Probe (location) to print in the email, so we don't know WHICH of the services is having an issue until we are able to log in and troubleshoot the issue further.
This is similar to how you can have one recording result in multiple transactions with the same name, and you can only tell them apart with the Playback Location.
