ahh, colgui. Now i'm remembering. One of the reasons I want to stop
supporting it is because it adds that many more permutations to test, If I
recall the reason I did -i0 -c1 was so that I could see the headers
returned by collectl. THat was long time ago because I had added the
--showcolheaders for colmux to use for just that purpose and never thought
to backport it. I suppose one option it to try to replace those switches
in the command with --showcolheaders and see what happens. At the very
least I will try to see what I can do to make -i0 work (or throw an error)
in the normal cases.
I might also try to run colgui myself for old times sake and see what
happens.
as an aside, the main reason I don't use colgui any more and haven't for
many years is because I can get anything I need in real-time with colmux
and alternatively near-real-time with colplot. Have you ever tried colplot
with a short refresh rate? Not real time but close AND the graphics are
much more detailed than colgui as well.
One other option if graphite. Does stellar graphics and i think I can do
things in real-time though i haven't personally tried. there IS a collectl
export module that will allow you to feed data to it, so perhaps that might
be an alternative as well.
