memory on vPar as shown in extract

[System Unix]

Hi,
I have noticed a strange thing on servers that are with vpar installed. ( I checked 3 different servers with ~3 vpars on each server).
I configure the reptall file with the following metrics:
DATA TYPE CONFIGURATION
GBL_NUM_CPU
GBL_MEM_PHYS

where i ran the command /opt/perf/bin/extract -xp -c -b today -r reptall the output varied every few lines form 18432 to 18416 in the Phys mem column.

the vpar status showed :

hpp711 0/ 0 18432 0/ 0 0
hpp711b 0/ 0 30528 0/ 0 0

any idea ????


thanks,
Reuven

Please note that this is a nebelous value as the value varies constantly especially with dynamic buffer cache but this should give you some ideas (if you have Glance installed):
