python script monitor

[Nicholas Cannon]

I have made an app that is not fully stable and I would like to monitor the performance of the app and try and improve the speed of it. I tried to use the activity monitor on the mac but what I want I'm to see how much ram, cup and other stats on what resources that app is using. Is there any apps to specifically monitor a certain app. I am on Mac is so any suggestions that could work with that would be great.
