Busiest Disc Files (System I/Os, by Volume)
(SIOBVOL)
•
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 report is sorted by volume name and descending total physical I/Os.
Busiest Disc Files (System I/Os, by Volume) (SIOBVOL)
This 132-column report shows the busiest disk files on each volume, in terms of
system I/Os (Measure driver calls) that may or may not be satisfied from disk cache.
The report includes:
•
File name
•
Total number of opens
•
System I/Os as percentage of volume total
•
Physical I/Os as percentage of volume total
•
Total requests blocked (lock waits) [not rated]
For total, input, and output:
•
System I/Os per second
•
Cache hit percentage
•
Physical I/Os per second (system I/Os minus cache hits)
The report aggregates all opens of the same file into one report line. All counts are in
units per second.
