Clarity - a log search tool By John Tajima & Tobi Lütke
Clarity is a Splunk like web interface for your server log files. It supports searching (using grep) as well as trailing log files. It has been written using the event based architecture based on EventMachine and so allows real-time search of very large log files. If you hit the browser Stop button it will also kill the grep / tail utility.
We wrote Clarity to allow our support staff to use a simple interface to look through the various log files in our server farm. The application was such a big success internally that we decided to release it as open source.
