Bucky – Open Source Real User Monitoring

Bucky is a client and server for sending performance data from the client into statsd + graphite, OpenTSDB, or any other stats aggregator of your choice.

It can automatically measure how long your pages take to load, how long AJAX requests take and how long various functions take to run. Most importantly, it’s taking the measurements on actual page loads, so the data has the potential to be much more valuable than in vitro measurements.
