mod_arm 0.05

mod_arm provides a simple, seamless, and application independent interface to ARM (Application Response Measurement).

mod_arm allows system administrators to get an accurate idea of how long an application takes on a running server - for a single instance or as a step in a multi-tier transaction. This is definitely a work in progress.
