Gathering Metrics from Your Infrastructure and Applications

January 8, 2018 Leave a comment


Understanding the state of your systems is essential for ensuring the reliability and stability of your applications and services. Information about the health and performance of your deployments not only helps your team react to issues, it also gives them the security to make changes with confidence. One of the best ways to gain this insight is with a robust monitoring system that gathers metrics, visualizes data, and alerts operators when things appear to be broken.

Building and Packaging a Python command-line tool for Debian

October 27, 2017 Leave a comment

Python packaging has a chequered past.

Distutils was and still is the original tool included with the standard library. But then setuptools was created to overcome the limitations of distutils, gained wide adoption, subsequently stagnated, and a fork called distribute was created to address some of the issues. Distutils2 was an attempt to take the best of previous tools to support Python 3, but it failed. Then distribute grew to support Python 3, was merged back in to setuptools, and everything else became moot!

Unfortunately, it’s hard to find reliable information on python packaging, because many articles you might find in a Duckduckgo search were created before setuptools was reinvigorated. Many reflect practices that are sub-optimal today, and I would disregard anything written before the distribute merge, which happened in March 2013.

While which packaging tool to use was ambiguous in the past, it’s now much easier to recommend one. At the time of writing (September 2016), you should use setuptools. It’s what most packages use, is fully supported by pypi and pip, and works pretty well. For a summary of the subject of python packaging tools, this page summarises them all very well.
