Aleksey Plekhanov updated IGNITE-28625:
---------------------------------------
Description:
Hit rate metrics like {{io.dataregion.default.AllocationRate}} now have "...
per second" in their description. It was true for deprecated
{{DataRegionMetrics}} JMX bean, since it was calculated as:
{{((float)allocRate.value() * 1000) / rateTimeInterval}}. But for "new metrics
framework" they return raw accumulated value per interval (not per second). We
should fix these metrics or metrics description and documentation.
Deprecated PagesReplaceAge metric calculated as "sum of all replaced pages ages
per interval" / "sum of all preplaced pages per interval", but now it's just
"sum of all replaced pages ages per interval".
