This is a slightly modified version of dowser from http://e-mats.org/2013/01/debugging-pythons-memory-usage-with-dowser/
Changes:
- Cherrypy integration replaced with aiohttp
- Python 2 is not supported anymore. Python 3 only (you should expect it with aiohttp)
- Added support for pympler to find heavy objects and measure object sizes
- Added support for tracemalloc to find memory allocations
- Added option to search only for types having at least N instances
- Added option to sort object types by instance count or total size
- Fixed displaying object info when its attributes cannot be represented
To integrate dowser to your aiohttp server, use:
import dowser
dowser.setup(existing_app)
This will bind sub-path /dowser/ to your existing aiohttp app.
Alternatively one can specify custom sub-path:
dowser.setup(existing_app, bind_path='/.secret-dowser/')
