Script to subtract numerical values from two (not only) numastat log files end.log minus start.log

numastat_diff

Script to subtract numerical values from two (not only) numastat log files end.log minus start.log

Example usage:

numastat > numastat.start ; COMMAND; numastat > numastat.end
numastat_diff.py--start numastat.start --end numastat.end

Output shows how numastat statistics has changed while running COMMAND, computing end-start for all numerical values.
