of these three options "page-sampling,dirty-bitmap,dirty-ring"
can be specified when calculating dirty page rate.

Calculate an active domain's memory dirty rate which may be expected by
user in order to decide whether it's proper to be migrated out or not.
The ``seconds`` parameter can be used to calculate dirty rate in a
specific time which allows 60s at most now and would be default to 1s
-if missing. The calculated dirty rate information is available by calling
-'domstats --dirtyrate'.
