Process Existence Timeline (PTIMLIN)
•
I/Os per seconds, of each type
•
Bytes transferred per second, in and out
•
Average bytes per I/O, in and out
•
Average milliseconds per physical I/O, in and out
This report uses the DGLOBAL, DISCINFO, and DISC 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 report is sorted by volume name and logical device number.
Process Existence Timeline (PTIMLIN)
This 132-column report displays the number of processes existing in each of 16 time
intervals. You can specify the width of the interval, in minutes, by the parameter,
PARAM INTERVAL mm, or it is computed by the query. The report includes:
•
Program file name
