Alert Tuning Wizard in SCOM 2016 needs a Path Column
When using the new alert tuning wizard in SCOM 2016 you often find that the alert source dialogue is utterly useless.
It only contains two columns, Source and Alert Count. The problem is that Source is often not enough to decide whether it's the right source or not.
For example, all alerts from database instances with default instance name are all listed as MSSQLSERVER, giving you a helpful dialog looking like this:
I have no idea what database instance I am tuning alerts on from that information.
The solution is simple, add a Path column.
