RackStatsD

Some tiny middleware for monitoring Rack apps in production.

  • RackStatsD::RequestStatus - Adds a status URL for health checks.
  • RackStatsD::RequestHostname - Shows which what code is running on which node for a given request.
  • RackStatsD::ProcessUtilization - Tracks how long Unicorns spend processing requests. Optionally sends metrics to a StatsD server.

Note: The request tracking code isn't thread safe. It should work fine for apps on Unicorn.

This code has been extracted from GitHub.com and is used on http://git.io currently.
