Integration with Graphite/Carbon

Graphite (http://graphite.wikidot.com/) is a kick-ass realtime graphing application built on top of three components: - Whisper - a data storage system - Carbon - a server for receiving data - A Python web application for rendering and managing graphs

The uWSGI Carbon plugin allows you to send uWSGI's internal statistics to one or more Carbon servers. It is compiled in by default as of uWSGI 1.0, though it can also be built as a plugin.

Quickstart

For the sake of illustration, let's say your Carbon server is listening on 127.0.0.1:2003 and your uWSGI instance is on the machine debian32, listening on 127.0.0.1:3031 with 4 processes. By adding the --carbon option to your uWSGI instance, your server will periodically send its statistics to the carbon server. The default period is 60 seconds.

uwsgi --socket 127.0.0.1:3031 --carbon 127.0.0.1:2003 --processes 4

The metrics are named uwsgi.<hostname>.<id>.requests and uwsgi.<hostname>.<id>.worker<n>.requests.

  • hostname will be mapped to the machine hostname
  • id is the name of the first uWSGI socket with dots replaced by underscores
  • n is the number of the worker process, 1-based.
