How to Find Instance Name for Availability Group Listener? I was recently asked this by DBA at  Comprehensive Database Performance Health Check. Well, the question is very valid if you are familiar with how Availability Group Listener works.
If you are connected to an Availability Group listener, the name displayed in Object Explorer and Properties may be different from what your instance name is actually. In this case, you may have to just use the T-SQL for the same.
Here is the T-SQL for the same.
SELECT @@Servername
Once you run the command above, it will give you a different server name from the Availability Group Listener name. Well, that’s it for today. What do you think of this small but very important blog post?
