nodejs-munin
A Munin stats catcher & plugin for node.js applications. Allows node.js apps to collect stats and report them on-demand to a Munin node.
Inspired by StatsD. StatsD uses Graphite, but I had an existing Munin-based graph infrastructure, so this works with Munin.
Still under development. Code was copied from a site where it's used in production, but is not yet generic enough for common use.
