Notice that host-2 and host-5 in your screen shot are showing 'purple' for everything other than 'conn'. This indicates the client software on each of them is not reporting in to the xymon server. If those clients aren't reporting in, it isn't surprising the other columns are empty.
But you don't describe how you expect the missing columns to be populated. Are those columns being populated by messages sent by your clients, or are they being populated by server-side analysis or tests?
It may be the test results are being generated and not sent. It may be the results are being generated and sent, but not matched to a host and displayed. It may even be the results aren't even being generated. We still need more information about your architecture.
If I had to throw a dart at the wall, my hypothesis is your test results are being submitted to the xymon server under a short hostname, while your clients are listed in hosts.cfg with a fully-qualified hostname. This is only one of many possible reasons, and is based on many unsubstantiated assumptions. I wouldn't even test this hypothesis without first knowing more about where the the missing messages originate. I know some folks prefer a more iterative approach to problem solving than I, so there's my wild guess.
Do the absent columns appear for other hosts? Yes
Do you expect all of the missing columns to be populated for all hosts in that display group, or only some of the columns on some of the hosts?
Have you confirmed these hosts are not in a "group-only" display group? How do I check this?
I doubt this is the case as your screen shot shows all the hosts in one display group. But to check, look in hosts.cfg and look for 'group-only' where you would otherwise see 'group'.
