I assume this data can then be requested via a standard HTTP request, 
i.e. it is available in a web browser ?

In that case, a simple http-test in Xymon would do it. Probably with an 
added content-check, e.g.

   10.0.0.1 nginx1 # \
       cont=nginx;http://nginx1/nginx_status;server.accepts.*requests

This will check that the data returned contains the "server accepts 
handled requests" string.

Don't know if it would make sense to track any of these in Xymon, but I 
see there is already a pointer in the Wiki to monitoring with rrdtool, 
so adding graphs shouldn't be at all difficult.
