Disc Cache 1 (Activity, by Block Size) (CACHE1)
Disc Cache 1 (Activity, by Block Size) (CACHE1)
This 132-column report displays disk volume cache utilization. The four groups of
columns provide the following information for each valid DP2 cache block size:
•
Blocks allocated
•
Blocks dirty
•
Cache hits per second
•
Cache misses per second
•
Cache faults per second
•
Audit buffer forces per second
This report uses the DISCINFO and DISC entities.
Parameters used are:
•
LID—specifies the Measure Load ID
•
SECTION—specifies the report section number
The report is sorted by volume name and logical device number.
The information on the report comes from the DISCINFO, DISC, and LDEV entities.
