psprofile 0.1.3

Collects resource usage of an executed script

Latest Version: 0.2


A python process profiler. Watches a process tree and emits resource usage metrics. Uses the psutil library, so runs on a mac and linux (haven’t tested Windows, but theoretically it will work). You will get slightly different fields back depending on the operating system. Used by the Cosmos Workflow Management System.


pip install psprofile


$ bin/psprofile -h
usage: psprofile [-h] [-o OUTPUT_FILE] [-i POLL_INTERVAL] [-w WAIT] ...
