How does linecount work?

Shirefolk:

I am playing with the nifty new 4.2 features, and was trying to get the "linecount" function to work. I *thought* I could maybe use this to track the number of entries in a file, and perhaps graph over time, but I am starting to suspect that Henrik meant linecount for something else.

I see where you configure client-local.cfg with:

linecount:<filename>
<handle>:<regex>

This should alert the Hobbit agent to start grepping <filename> for <regex> and somehow bind the count to <handle>?

Then what? Do you configure something in hobbit-clients.cfg to match this?

I tried:

LOG <filename> .* COLOR=GREEN

To see what would happen, but nothing did...
