Ostrich is a small library for collecting and reporting runtime statistics and debugging info from a scala server. It can collect counters, gauges, and timings, and it can report them via log files or a simple web interface that includes graphs. A server can also be asked to shutdown or reload its config files using these interfaces. The idea is that it should be simple and straightforward, allowing you to plug it in and get started quickly.
