bench 1.4

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

> monitor.py  sleep 2
PID Prog    UsrTime SysTime RealTime        MaxVms  MaxRss  AvgVms  AvgRss  Path    Command
21056       python  0       0       1.9     77705216        6696960 77705216.0      6696960.0       /home/zhanxw    "/home/zhanxw/python27/bin/python /home/zhanxw/bin/monitor.py sleep 2"
21057       sleep   0       0       1.8     7581696 368640  7581696.0       368640.0        /home/zhanxw    "sleep 2"
21054       python  0       0       2.1     77705216        6991872 74768556.8744   6687656.42056   /home/zhanxw    "/home/zhanxw/python27/bin/python /home/zhanxw/bin/monitor.py sleep 2"

• Example 2: complex shell commands

> 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
21920       python  0       0       3.9     77713408        6701056 77713408.0      6701056.0       /home/zhanxw    "/home/zhanxw/python27/bin/python /home/zhanxw/bin/monitor.py -i 0.1 sleep 2 & sleep 4 & seq 1000000 >/dev/null & wait"
21921       sh      0       0       3.8     12886016        1417216 12886016.0      1417216.0       /home/zhanxw    "sh -c sleep 2 & sleep 4 & seq 1000000 >/dev/null & wait"
21922       sleep   0       0       1.8     7581696 368640  7581696.0       368640.0        /home/zhanxw    "sleep 2"
21923       sleep   0       0       3.8     7581696 368640  7581696.0       368640.0        /home/zhanxw    "sleep 4"
21924       seq     0.55    0       0.4     7602176 630784  7602176.0       630784.0        /home/zhanxw    "seq 1000000"
21918       python  0       0       4.1     77713408        7000064 76043060.5519   6826628.73828   /home/zhanxw    "/home/zhanxw/python27/bin/python /home/zhanxw/bin/monitor.py -i 0.1 sleep 2 & sleep 4 & seq 1000000 >/dev/null & wait"

NOTE

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

This version requires psutil.
