Memory consumption history

I want to obtain memory consumption history on a HPUX machine.
I know I can access data from the last week with sar
sar -f /var/adm/sa/sa14

I do not know how to get memory usage with sar.

Are there any other ways?

thank you

Unless something has been logging it, you won't get it.

man sar

as I said, I already done that and in hp-ux I canot see how can you get memory stats with sar (just some swap stats, but that's not what I need).
