Yes, IgniteVM shows you the waits, same as Ignite8 would do.

The reason I don’t look at waits first is because I want to make certain I rule out the “noisy neighbor”. If my host has disk saturation, then knowing my query is waiting for disk won’t help me make that query faster. I want to address the root cause of performance problems, and not the symptoms or effects.

Even though you are trying to sell a product you have provided very good information. 

Since it takes microseconds to run a good waits query… why wouldn’t you do that first? It doesn’t seem like a waste of time if you have a properly balanced virtual environment. 

Does IgniteVM show you the waits?
