Focuslight

Focuslight is a lightning Fast Graphing/Visualization tool, built on RRDTool. It is a Ruby clone of GrowthForecast.

Focuslight is compatible with:

• stored data files
  • database (sqlite) and graphs (rrdtool)
• almost all HTTP API requests, except for:
  • complex graph creation
  • export support

Focuslight is currently lacking some GrowthForecast features:

• MySQL support
• Disabling Subtract
