SQL SERVER – Fixing Freezing Activity Monitor

The other day I had a very interesting experience while working with my client on Comprehensive Database Performance Health Check. While doing performance tuning, I personally prefer to use DMVs and DMFs but for the visualization easiness client preferred Activity Monitor which due to some reason was Freezing suddenly for him. After a while, we figured out a solution for the same and it was a simple permission issue.

While working together DBA from my clients’ side noticed that the Activity Monitor was freezing for a few servers. It was indeed a very interesting problem. After a while, we figured out that it was just a permissions issue and very easy to fix it. Let us see how we were able to fix it with the help of images.
