Thank you Todd for your reply, but if I understand well, the following
WLM view of SYSVIEW uses WLM RCAA for the values of I/O count, connect
time, ... as I retrieve the same values using IWMRCOLL/RCAE but it uses
another control block for the average values (didn't find EMCB in data
areas documentation) ?
Resource Value Average
Total service units for period 82495
CPU service units 77274
SRB service units 5221
...
DASD I/O count 19661
DASD I/O connect time 3.527936 0.022968
DASD I/O disconnect time 1.666304 0.010848
DASD I/O wait time 0.000896 0.000006
Sorry if I understand badly...
Nevertheless, reading the RCAA RCAEIORC comment /"Total DASD I/O count.
This can be used with fields RCAEIOCT, RCAEIODT, RCAEIOWT, RCAEIOST to
determine average DASD response time for the period"/ it seems possible
to obtain average value with these fields. The solution is by using
"multiply by 128" method from Graham ?
Thanks
Guillaume

The DASD service times calculated by SYSVIEW do not use the WLM control blocks.
SYSVIEW uses the data found in the EMCB control blocks.
The times and counts shown in SYSVIEW can be viewed in real-time over the last
hour in 1 minute intervals.
Within SYSVIEW, you can view this information using the following commands:
1. DASDRESP - SYSVIEW collected information
2. RMDASD - RMF information
The data shown in each will be very similar. The difference will be based on
the timing of the collection.
