vmstat - Getting application memory & CPU usage

Danny Fang — Wed, 24 Aug 2005 07:00:32 GMT

Hi,
I'm attempting to get the amount of memory and CPU used for a particular application by running vmstat(see attached file for output).

I would like to obtain the amount of active memory used when running vmstat, by specifying the -a option(amt of active and inactive memory
bash-2.03$ vmstat -a 10 10
Usage: vmstat [-cipsS] [disk ...] [interval [count]]
bash-2.03$ vmstat -a 10 10

I would like to know if getting the active memory usage would represent the amount of memory used in MB for a particular application?

Also, if I wish to see the CPU utilization from vmstat, may I know if I should refer to the "usr" or "sys" columns under the heading cpu?

Could anyone help me out?

Thanks

AFAIK, you cannot "to get the amount of memory and CPU used for a particular application" with vmstat, but only using ps or top utilities.
