Description:

process plot 0.5.2

process-plot

Create plots of resource usage for a process (memory, CPU, etc).
Process statistics are polled at a set interval, in a cross-platform manner (i.e. supports Linux, OSX and Windows).
Information is collected on both the main process and any child processes, and can be plotted in a single graph.
Usage
Install the package with pip or pipx:
$ pipx install process-plot

then run:
$ pplot exec "sleep 1" -i 0.1
PPLOT INFO: Output files will be written to: /user/pplot_out, with basename: 20210921125420
PPLOT INFO: Running process as PID: 5379
PPLOT INFO: Total run time: 0 hour(s), 00 minute(s), 01.034680 second(s)
PPLOT INFO: Plotting results to: pplot_out/20210921125420.png
PPLOT SUCCESS!

You will then find the output files in /user/pplot_out, with a plot for the process like:

If the process spawns child processes, by default, the values for the main process and all child processes are summed together.
When called with --stack-processes, the plot will stack the values per process:
$ pplot exec "parallel sleep ::: 2 2 2" -i 0.2 --stack-processes --legend

Additional options are available:
$ pplot exec --help

Usage: pplot exec [OPTIONS] COMMAND

Execute a command and profile it.
