Erik Darling has a video for us. There’s no graf that I can include here, so I’m stuck having to come up with my own explanation…
This is an interesting video covering a fairly new feature in sp_WhoIsActive, as well as giving us some good information around the numbers meaning pages rather than (something)bytes, yet the memory_info column gives us results in kilobytes.
Also, be sure to grab version 12 of WhoIsActive.
