Memory – Tool for Logging Memory Usage

memorymonitoring

I want to monitor memory usage of a process, and I want this data to be logged. Does such a tool exist?

Best Answer

I have written a script to do exactly this. It basically samples ps at specific intervals, to build up a profile of a particular process. The process can be launched by the monitoring tool itself, or it can be an independent process (specified by pid or command pattern).

something to get you started (just in case you want to write it yourself):

#!/bin/bash
#
# usage: bwmon PID

IN=0; OUT=0; TIME=0

get_traffic() {
    t=`awk '/eth0:/ { printf("%s,%d,%d\n",strftime("%s"),$2,$10); }' < /proc/$1/net/dev`
    IN=${t#*,}; IN=${IN%,*}
    OUT=${t##*,};
    TIME=${t%%,*};
}

get_traffic $1
while true
do
    _IN=$IN; _OUT=$OUT; _TIME=$TIME
    get_traffic $1
    echo "$TIME,$(( $TIME - $_TIME )),$IN,$(( $IN - $_IN )),$OUT,$(( $OUT - $_OUT))"
    sleep 1
done

comments:

checks only eth0
checks every 1 second
works only under linux, but other unixes work similar (procfs or whatever)
output could be stored into a sqlite.db with stat --printf="%N\n" /proc/PID/exe | cut -d ' ' -f 3
