pyramid_scales

The excellent scales library to collect in-process metrics (see Coda Hale’s CodeConf talk "Metrics everywhere" among many others for reasons why you might want use it) comes with a flask-based HTTP server that allows viewing the collected measurements and dumping them as JSON. But if you already are in a web application using pyramid, there's no real need to spin up yet another thread, open another port etc. to do this.

Instead, you can simply include pyramid_scales like so:

import pyramid.config
config = pyramid.config.Configurator()
# rest of your configuration goes here
config.include('pyramid_scales')

This registeres a view below the URL /scales/ where you can view your application's metrics. If you need more control, register the pyramid_scales.scales_stats view yourself in whichever way you need.

This package is compatible with Python version 2.7 (scales itself does not support Python3 yet, so there's no point here).
