Description
There are various SQL stats that are sampled in SQL Activity (e.g., contention, P90s, etc.) which has caused confusion when correlating across these stats with non-sampled stats. We should call out the sampled stats in the tooltip including their sampling rate as well as update our documentation with this behavior.
