[Xymon] Trying to set up a custom graph

Mon Jul 18 19:31:47 CEST 2022

Nevermind, it seems I was trying to use trends last week and my attempts to
send data were kinda goofy and not working well.

Rewriting my task script seems to have fixed the issue.  I have now both
cfbytes and cfconns columns on my status page.

Thanks,
Matt
