old style log dredging PMDA

[Ken McDonell <kenj@xxxxxxxxxxxxxxxx>]

Once upon a time we had (Mark wrote I think) a pmda that camped on the 
end of a log file basically doing a tail piped into a grep selection to 
accumulate counts of different sorts of log lines.
It also handled log rotation.

Does anyone else remember this, or am I dreamin' again?

If it did exist at one time, anyone know where to find it now?
