How to retrieve the global state of Xymon?

Hello,

my current project is (trying to) display the global state of Xymon, that is the state (colour) shown in the main view. A sort of a traffic light is used, which is controlled by an ESP8266 micro controller running microPython.

This state must be determined from the states of all the tests, which can be retrieved using the 'xymondboard' command. As far as I know, there is no other way of retrieving the global state of Xymon. Is this correct?

The NOPROP* tags seem complicate things. One can retrieve the tag(s) per host, using f.i. 'xymondboard fields=...,XMH_NOPROPRED', but the tag is shown, not the result of combining it with the command line parameters of xymongen. Is there another way of retrieving this information?

Kind regards,

  Wim Nelis.
