Is there an easy (or even medium hard) way to merge the content of two hosts? I updated the entry for a server in Xymon to a fully qualified hostname, but the server is identifying itself with an unqualified hostname, and putting the CLIENT: tag fixed it, but for some reason, it seems to have lost track of the prior history. :/

It depends slightly on what you mean here as the history files are stored in separate places, either as separate files in the directory (snapshots, historical status messages, RRD files), or lines in the history file.

You should be able to simply move the former files into the properly-named directories (you'll lose RRD data points since the transition, but merging RRDs is a major headache...), but if you want this history timeline to cover the recent period as well you'll want to append those lines to the previous one. (The history file is what's read in when you click the History button on any status page.)

All of these files are located in the various directories underneath $XYMONVAR (/var/lib/xymon/ in the RPM), so a 'find' command looking for the old hostname should help you find any stragglers there.

And of course, you'll want to make sure the FQDN is listed properly in hosts.cfg.
