Why not run the actual 'top' command in batch mode with only one
iteration? It's in the man page. I'm referring to this:
status = os.popen('top -b -n 1').readlines()
Also, the following approach seems to display a nicer output:
-------------------------------------------------
#!/usr/bin/env python
import os
status=os.popen('top -b -n 1')
for i in status.readlines():
print i
-------------------------------------------------
Or how about the following?
-------------------------------------------------
#!/usr/bin/env python
import commands
status=commands.getoutput('top -b -n 1')
print status
-------------------------------------------------
Mind you, I'm just suggesting different approaches. I'm new to Python
and don't necessarily know what I'm doing. Other more experienced
people may be able to suggest something better.
