WSGI middleware to measure the memory footprint of GAE Python applications.

Project Description

The apptrace package provides a WSGI middleware for tracking memory usage in Google App Engine Python applications.

Since apptrace is meant for development and debugging purposes only, it works with the development appserver of the Google App Engine Python SDK and TyphoonAE. It will definitely not work on the GAE production environment.


The apptrace package requires Guppy-PE ( to be installed on your PYTHONPATH. It will be automatically installed when you use the easy_install command.


The easiest way to install apptrace is (provided that you have setuptools installed) to use easy_install apptrace.

Running Apptrace

In order to run the demo application with apptrace run following commands:

$ apptracectl init demo
$ python demo

See this wiki page for a more detailed documentation on using apptrace:


If you want to tinker with the most recent development version of apptrace, install the development environment by typing following commands:

$ hg clone apptrace-dev
$ cd apptrace-dev
$ python --distribute
$ ./bin/buildout

Running Unit Tests

All unit tests can be run by executing the following command:

$ ./bin/python test --appengine-path=<path to the SDK>
