Clarity

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 in realtime. 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.

SECURITY:

Warning: Clarity takes parameters from URLs and runs them in the shell. This is essentially the most insecure thing imaginable. You have to make absolutley sure that clarity isn’t reachable by the outside world. At the very least use –username and –password to put some protection on it.

USAGE:

clarity --username=admin --password=secret --port=8989 /var/log
