Speaking off the top of my head, which means I'm probably missing
something...

I think you'll have to put the data into a single file (one LUN
per column) for this to work.  As I remember, orca makes one plot
per file, with no way to stick multiple files together.

So, I'd say you want some way to make the multiple files
you get and convert them into a single source file for
giving to orca.  I can think of a bunch of different ways
to do that - none of them perfect, but they'd work
(in effect: tail all the files, and when all files have
new data (or when new data has arrived for at least one file
and <x> minutes have passed), take the data from each file
and create a row for the group file.  The other option would
be to create this group file from scratch every time, but I
really don't like that idea either...)
