bench 1.2

Benchmark resources usage

Monitor Process Resources Usage

Bench is able to monitor:

• CPU time (user time, sys time, real time)

• Memory usage (vms usage, rss usage)

• Output to TSV(tab-delimited files)

Examples

• Example 1: simple command

> python ../monitor.py sleep 2

PID Prog    UsrTime SysTime RealTime        MaxVms  MaxRss  AvgVms  AvgRss  Path    Command
14264       python  0.0     0.0     NA      NA      6728    NA      NA      /home/zhanxw/mycode/bench/bench "python ../monitor.py sleep 2"

• Example 2: complex shell commands

> python ../monitor.py -i 0.1 'sleep 2 & sleep 4 & seq 1000000 >/dev/null & wait'

PID Prog    UsrTime SysTime RealTime        MaxVms  MaxRss  AvgVms  AvgRss  Path    Command
13849       seq     0.48    0       0.4     7356416 634880  7356416.0       634880.0        /home/zhanxw/mycode/bench/bench "seq 1000000"
13845       python  0.54    0.0     NA      NA      6728    NA      NA      /home/zhanxw/mycode/bench/bench "python ../monitor.py -i 0.1 sleep 2 & sleep 4 & seq 1000000 >/dev/null & wait"
13847       sleep   0       0       1.9     7335936 368640  7335936.0       368640.0        /home/zhanxw/mycode/bench/bench "sleep 2"

NOTE

Shell (/bin/sh) are used to execute commands. It’s a convenient feature with some shell exploit hazard.

This version requires psutil.
