Hello,

Am working on small program that used to calculate the memory usage of AIX servers. Am using svmon -G command to get the memory usage. For example, consider the following output.

$ svmon -G
size inuse free pin virtual mmode
memory 1957888 670177 1287711 411476 512709 Ded
pg space 131072 2929

work pers clnt other
pin 350964 0 0 60512
in use 512709 0 157468

PageSize PoolSize inuse pgsp pin virtual
s 4 KB - 269713 2929 85684 112245
m 64 KB - 25029 0 20362 25029
$

Am using "in use" value at the 6-th line number as memory usage. It gives 26 % as a memory usage. Also am using /bin/ps -eo comm,pmem,args to get the all the process memory usage to confirm with previous calculation.But value calculated by both methods does not match.

Please advise.

Depending on what metric you are trying to monitor the number directly below InUse in the first column might be a better number. The lower numbers are details about the numbers in the first (numeric) line.

I would suggest a slight variation to your command:

michael@x054:[/home/michael]svmon -G -O unit=auto
Unit: auto
