Hi,
I was wondering if it possible to write a python wrapper which will account my
processes. I would like to account for all the children processes (fork) by
looking at their /proc/<pid> info. Such as memory, io, open files, stats.
So, instead of me running "/bin/sleep 10", i would like to run it as "pywrap.py
/bin/sleep 10" and it will do an exec /bin/sleep 10 and do a periodic snapshot
for whats in /proc/<pid>/stats.
Something like this is approximately the right structure for such a program.
#!/usr/bin/env python
import sys
import subprocess
import time
PERIOD = 1.0 # seconds
def check_stats(pid):
# You will have to implement this.
# Check out psutil:
# https://pypi.python.org/pypi/psutil
print 'Checking process {0}'.format(pid)
def main():
cmd = sys.argv[1:]
p = subprocess.Popen(cmd)
while p.poll() is None:
check_stats(p.pid)
# There are more accurate ways to do this, but this probably
# suffices for you.
time.sleep(PERIOD)
if __name__ == '__main__':
main()
