I spent my last evenings hacking on a new Graylog2 feature which will be very useful for running powerful analytics on your log messages: The Graylog2 Analytics Shell. The detailled description is in the wiki.

Use this shell to extract information from your log messages. I always like the use case of API monitoring. You could easily find out if that one call is still used by consumers - Or even which consumers are still using it with a simple distinct call:

all.distinct({_oauth_consumer_key}, processed_controller = /^PrivateMessages#.+/)

Watch the shell in action in this short screencast: (Try the full screen mode and HD video)

This is the first working implementation but there is still stuff missing. For example:

• Shell history available with up and down arrow keys
• Improved design and layout
• A history of count and distinct results
• Tab completion (ZOMG!!)
• Saving and sharing of commands
• Short names for streams, to avoid typing the raw stream ID

The shell will be included in the next version: 0.9.6

Post your comments here or discuss in the mailing list.

I wrote a shell script that lets me easily create new Graylog2 releases. It bundles Rails with all required gems, configures the release, works on some files and creates a nice .tar.gz package I can test and upload as release.
