An apache2 module to track and display performance information, grouped by URI

mod_telemetry keeps track of all URLs on your site and how long it takes your
server to deliver each request. It reports these by using a status handler
(like /server-status) to display real-time status information about the
performance of your site.

It is extremely useful in optimizing back-end processes (for example, when
connecting to Java, FastCGI, or Ruby back-ends) to identify when specific pages
are performing slowly.

Because it runs in the server, it's able to show end-to-end performance on each
request

It requires that mod_status be enabled to work.
