Careful on the CouchDB stuff: the write performance is atrocious over
a sustained period.  I couldn't get a single-node install to receive
more than a few hundred events per second.  MongoDB will give you a
sustained few thousand writes per second, depending on how many
indexes you've created on the collection.  Even writing JSON blobs to
any traditional database works surprisingly well for most uses,
especially if you have it write to a few key-value columns for quick

In the near-term, as I talked about at the workshop, I'll be
announcing an official ELSA release early next week which will read
syslog and handle grepping, basic reporting, and alerting for you from
a web interface.  (I didn't get to cover alerting in the talk, but
it's fully integrated as well.  There's also a CLI interface I didn't
cover, so you can use it like bro-cut.
