As per title, I check the export field document and seems like the "mongodb.collstats.queries.time.us" is the right one.
the problem I see is that since the metrics gathered are cumulative those values do not represent individual times, that's why my graph looks incremental
Do I need to do the dividing like below?
"mongodb.collstats.queries.time.us" / "mongodb.collstats.queries.count"
