Hello,
I am trying to capture performance data with cp3kvmxt and I am having
trouble to get anything more than CPU utilization.
The person who imports the EDF file says that his tool can't see storage
configuration for other LPARs and that it should. He can see storage
utilization only for a local z/VM instance.
The CPU utilization and configuration is there for all LPARs though.
Does monwrite data even contain storage information from other LPARs? I
don't remember seeing anywhere in performance monitor toolkit this
information and it uses same mondcss after all. In perfkit all I can see is
CPU stats from other LPARS (menu 8).
Here is what I do.
I have a user id with following directory statements required for using
mondcss:
IUCV *MONITOR MSGLIMIT 255
NAMESAVE MONDCSS
>From the userid id I did enable all necessary monitor domains:
q monitor
MONITOR EVENT ACTIVE BLOCK 4 PARTITION 8192
MONITOR DCSS NAME - MONDCSS
CONFIGURATION SIZE 68 LIMIT 1 MINUTES
CONFIGURATION AREA IS FREE
USERS CONNECTED TO *MONITOR - PERFSVM
PERSMAPI
MONITOR DOMAIN ENABLED
PROCESSOR DOMAIN ENABLED
STORAGE DOMAIN ENABLED
SCHEDULER DOMAIN DISABLED
SEEKS DOMAIN DISABLED
USER DOMAIN ENABLED
ALL USERS ENABLED
I/O DOMAIN ENABLED
PCIF CLASS ENABLED
ALL DEVICES ENABLED
NETWORK DOMAIN ENABLED
ISFC DOMAIN ENABLED
APPLDATA DOMAIN ENABLED
ALL USERS ENABLED
SSI DOMAIN ENABLED
MONITOR SAMPLE ACTIVE
INTERVAL 1 MINUTES
RATE 2.00 SECONDS
MONITOR DCSS NAME - MONDCSS
CONFIGURATION SIZE 4096 LIMIT 1 MINUTES
CONFIGURATION AREA IS FREE
USERS CONNECTED TO *MONITOR - PERFSVM
PERSMAPI
MONITOR DOMAIN ENABLED
SYSTEM DOMAIN ENABLED
PROCESSOR DOMAIN ENABLED NOCPUMFC
STORAGE DOMAIN ENABLED
USER DOMAIN ENABLED
ALL USERS ENABLED
I/O DOMAIN ENABLED
PCIF CLASS ENABLED
ALL DEVICES ENABLED
NETWORK DOMAIN ENABLED
ISFC DOMAIN ENABLED
APPLDATA DOMAIN ENABLED
ALL USERS ENABLED
SSI DOMAIN ENABLED
The mondscss segment size according to my calculations is pretty big:
q nss map
..
0012 MONDCSS CPDCSS N/A 09000 0CFFF
..
0CFF-09000=16383 (decimal) and 16383*4K (+1page) pages gives 64MB if I am
doing the math right.
I run the CP3KVMXT with mondcss argument and specify intervals and
timeframes manually (30 minutes intervals for 5 hours total run)
When it is done, it creates a bunch of files like:
D111815 ACTVUSRS A1
D111815 BCUDATA A1
D111815 DEBUG A1
D111815 EDF A1
D111815 SAMPS A1
There are no errors.
I've also tried to run monwrite first and use the result file as an input
for cp3kvmxt. Also no luck.
The EDF is the one I send to person with the tool to analyze it.
What am I doing wrong?
Thank you
Gregory
