There is a predefined alarm for this event called NEW_SERVICE. Just make sure it is enabled (in RUM Console -> Alert management). Once enabled you'd see events triggered by this alarm in Alert log (Diagnostics section), but you may also setup email or SNMP trap notifications.
See also into the whole list of predefined alerts if you need anything else.
ps. The above is valid for version 2017. In 2018 release alerting system has changed and we do not provide many of these predefined alerts out-of-the-box anymore. DOC chapter about alerting system is a bit outdated in that area (it's on Tech Comm's plate already to correct this)
