Full Discussion: Script to record max memory usage of program
Top Forums Shell Programming and Scripting Script to record max memory usage of program Post 303021454 by MadeInGermany on Thursday 9th of August 2018 01:34:13 PM

When a page fault occurs then something is paged in or out, usually from or to the swap space.
If you run
Code:
vmstat 2

you see it listed as si (swap in) or so (swap out).
Here is a suggestion for a bash script that monitors a given PID, and displays the maximum RSS memory (kilobyte of RAM used).
Code:
#!/bin/bash
[[ $1 =~ ^[0-9]+$ ]] || {
  echo "usage:
  ${0}: <pid>"
  exit 1
}
pid=$1
ps -fp $pid
max=0
while :
do
  rss=$(ps -o rss= -p $pid)
  if [[ $rss -gt $max ]]
  then
    max=$rss
    echo "maxRSS (kb): $max"
  fi
  sleep 10
done
