[Xymon] Xymond and xymonnet quirks

For the xymonserver.cfg, what is the proper way to configure when you have 2 xymon servers (1 primary and 1 instant backup server that gets the same data from all the reporting clients)? Should I change it from multiple to single in the xymonserver.cfg? but still have both listed in the xymonclient.cfg?

Spot on - that is how it should be done. A Xymon server really should only be reporting to itself, not to other Xymon servers.
