Holding and Pruning WhoIsActive Results

Andrea Allred has a script for us:

Last month I talked about how I started collecting data from sp_whoisactive. The long term goal was to analyze and tune those long running processes that are sometimes hard to quantify in Query Store. We had started collecting the data in a table (whoisactiveLog), but wanted to make a simple table that our Engineers could refer to and find the long running processes. We also wanted to archive off the whoisactiveLog into another table and save that for 70 days in case it was needed for further research on the tuning of processes. Each night, we have a break in our processes where we can do this maintenance so we decided we would empty the whoisactiveLog table completely.

There’s also a check for session length in there.
