Disc File Physical I/O Shares (DFPIOS)
This chart uses the GLOBINFO and DOPENSUM entities.
Parameters used are:
•
LID—specifies the Measure Load ID
•
EXCLUDE—specifies a value under which to exclude the number of requests per
second
•
SECTION—specifies the report section number
The chart is sorted in descending order of total driver calls.
