[Xymon] [PATCH] - xymonserver - all ok message - part 2

[SebA]

Hi John and list,

This sounds like some good patches, so I thank you for sharing them!

I had some related ideas as a result:

   1. Calculate numbers of green, yellow, red, purple, blue and clear tests
   - I think this is already done as they are on the xymongen page - and make
   those figures available via variables in the same way.
   2. Add similar (to XYMONALLOKTEXT) configurable text (via a different
   variable) to the non-green page, red page, and main page.
   3. Default to, or add an example of how to: display the number of reds,
   yellows and purples to the non-green and red pages.
   4. Default to, or add an example of how to: display the number of reds,
   yellows, purples, blues, clears and greens to the main page.
   5. I believe all these variables are available on the xymongen page
   already, and they are in ncv format so maybe it's possible to get xymon to
   graph them already, but I think a graph with all those variables on would
   be good for management.  If anyone has the configuration for it, I think it
   would be worth sharing it and adding to Xymon by default (in some release).

Kind regards,

SebA
