We got to 2 solutions for it:

  *   print to reader of a user: pipe vmc perfsvm print user (to SOMEUSER
  *   print to file on perfsvm: PIPE vmc perfsvm PRINT USER (SORT %CPU PAGESIZE 
OFF TOFILE XYGUEST LISTING A CLOSE

The last one also gets a listing without headers in between, both are also not 
limited to 80 bytes width, you get the same as with perfkit on the screen. We 
needed some columns far beyond the 80th column for displaying in Xymon.

Onderwerp: [CMS-PIPELINES] PIPE VMC buffer size

Hi All,

The PIPE VMC stage apparently has a fixed 8K buffer, though I don’t know for 
sure if that limit is in the VMC stage or a limit in the Performance toolkit. 
When retrieving data it only returns 101 records of 80 bytes as 101 records 
fills that 8K buffer.

When I run PIPE VMC USER with more than 100 users in z/VM it will discard the 
last records. And in our CPC we have a number of LPARs, with multiple CPUs, so 
PIPE VMC LPAR also discards the records after record 101.

Is there a way to increase the buffer size, perhaps similar to the buffer size 
of the CP stage?
