[Xymon] Trying to set up a custom graph

[Matthew Goebel]

Hey,

  Sorry, I was a bit frustrated and probably not being very clear.

  Yes, I am trying to follow the instructions located at :
https://xymon.sourceforge.io/xymon/help/howtograph.html

  I've got the data being sent to the xymon server and it is generating rrd
file entries.

  What I'm not seeing is the column named cfbytes on the "Main View" xymon
web page.  Not sure how to figure out why this is not showing up.

  I have confirmed that your rrdtool graph command is working for the rrd
file in question.

Thanks,
Matt
