The idea is pretty simple - I would love to see alerts that are specified for a Alert Group send notifications to different Contact Groups depending on the server that raised the alert, without having to duplicate the alert.
Here is an example. Lets say I have 5 servers in North America, and 5 in Asia. I create two alert groups - NA_SQL_Servers, and APAC_SQL_Servers. I also create two Contact Groups - NA_DBAs, and APAC_DBAs.
I create an alert. I assign the alert to the two Alert Groups. The feature I would like to see would allow me to notify the NA_DBAs if the alert was raised by a server in the NA_SQL_Servers alert group, and notify the APAC_DBAs if the alert was raised by a server in the APAC_SQL_Servers alert group
