smaps is an useful file to inspect the memory footprint of the process in linux.
It shows the memory mapping entries of a given process.
This tool simply parses 4 values and sums up the memory used from the same file:
- Private Clean
- Private Dirty
- Shared Clean
- Shared Dirty
- Use with a process name (automatically get the first pid by
pidof)
$> python parse_smaps.py -p smbd
