Thinking about my favorite feature in Foglight is like thinking about my favorite food. One of the hardest things to do in database management is to evaluate performance deviation across time. The adaptive baseline that Quest is using is by far the most helpful. That doesn't necessarily mean I use it on a daily basis, but it is something that I have not been able to find in any other tool, at the same level. Microsoft and Query Store do provide performance monitoring. There are a lot of legacy, built-in, free-of-charge tools that do part of the job, but not as comprehensively. Foglight's adaptive baseline monitoring and measuring of deviation is one of the best features of the solution.
