Recording Memory Footprint In Linux

Question

Is there a way we can record memory footprint? In a way that after the process has finish we still can have access to it.

The typical way I check memory footprint is this:

$ cat /proc/PID/status

But in no way it exist after the process has finished.

Answer 1

you can do something like:

watch 'grep VmSize /proc/PID/status >> log'

when the program ends you'll have a list of memory footprints over time in log.
