Python - Graphite: Storage and Visualization of Time-series Data

I'm doing some work with Graphite in Python. Here is a quick overview of what Graphite is...


Graphite provides real-time visualization and storage of numeric time-series data.

Graphite does two things:

  • Store numeric time-series data
  • Render graphs of this data on demand

Graphite consists of a storage backend and a web-based visualization frontend. Client applications send streams of numeric time-series data to the Graphite backend (called carbon), where it gets stored in fixed-size database files similar in design to RRD. The web frontend provides 2 distinct user interfaces for visualizing this data in graphs as well as a simple URL-based API for direct graph generation.

Graphite consists of 3 software components:

  • carbon - a Twisted daemon that listens for time-series data
  • whisper - a simple database library for storing time-series data (similar in design to RRD)
  • graphite webapp - A Django webapp that renders graphs on-demand using Cairo
