Thanks all for your comments! I'm working on some fixes (and silly
RE typos ;-) ) that Hans mailed to me independently.

I'm also currently working on keypress input, to allow this sort
of thing. It will soon hopefully be able to run without tail - I'm
adding select to enable it to watch multiple files.

That's similar to an idea that is on the list. The data structure
already contains extra information for each statistic (all
messages that made up the stat in the last 5 minutes, and at least
5 messages if it's been around longer than that, IIRC). The
difficult bit will be the curses handling to make it work...

I like the idea to match on a pattern. Will see how that goes.

It really needs some way of auto-detecting anomalies in the data,
so it can alert. That's going to be hard for me to work out as
anything to do with statistics makes my brain rapidly
disintegrate. If anyone has any hints they would be most
appreciated!

Cheers,

Matthew
