I've run into this same issue and am curious about the answer. My understanding from reading the docs is that the CLASS definition in hosts.cfg is supposed to override the class setting being sent back from the client.
CLASS:Classname Force the host to belong to a specific class. Class-names are used when configuring log-file monitoring (they can be used as references in client-local.cfg(5), analysis.cfg(5) and alerts.cfg(5) to group log file checks or alerts). Normally, class-names are controlled on the client by starting the Xymon client with the "--class=Classname" option. If you specify it in the hosts.cfg file on the Xymon server, it overrides any class name that the client reports. If not set, then the host belongs to a class named by the operating system the Xymon client is running on
I read that as if I didn't add the --class argument to the xymon client command then what is in hosts.cfg should be the class used. However, this seems to not be the case (although I would argue that it should work this way).

Under Xymon 4.3.25, I'm trying to use the class attribute to group hosts together by what monitoring and alerting they need.
So for each host I have a hosts.cfg line like: 192.0.2.1 somehost.example.com # CLASS:Foo trace ssh
Then in analysis.cfg I have: CLASS=Foo PROC this PROC that
And alerts.cfg has: CLASS=Foo SCRIPT=blah
However, the tests in analysis.cfg are not being applied. If I replace CLASS=Foo with HOST=somehost.example.com they work as expected. Also, CLASS=linux seems to work, which implies that the CLASS: directive in the hosts.cfg is being ignored.
As far as I can tell, the messages on xymon's "client" channel don't contain the class name that was specified in hosts.cfg, so xymond_client is using the class that the client sent instead. Other channels, such as "status" do include the class name that was specified in hosts.cfg.
Am I misunderstanding how the class is supposed to be used, or is this a bug?
