I finished my masterpiece hosts.cfg and have had my xymon server up and running for a while but now that I've got client data coming in, I've noticed some very strange behavior. When I have the host on the front page, all tests show up fine. When I move the host to a page (first level, using the page command) the tests that depend on client data go "purple" and the data doesn't update. Also: hosts on pages cannot be seen when I click the "info" column and they're not seen in enable/disable tests either, even when I click on that option from the page they show up on. I've tried explicitly setting the groups they're in to display the "missing" data but it doesn't help. I have made some changes... but none that I think would/should be affecting it like this.
I've changed the xymonclient-linux.sh script to use different commands, like adding the -h switch to df, or changing MACHINEDOTS="hostname -s | tr [:upper:] [:lower:]" (always a short name, always lower case, to address inconsistencies) but as soon as I move them back to the front page, the data shows up again and they're "green". The data from when they were "missing" still shows as missing in the history... I'm stumped on this one. I'm relatively certain the only changes I've made server side are only cosmetic changes to the underlying HTML and CSS files.
I'm using the terabitha RPMs for my server and built from source for my client:xymon.x86_64 4.3.26-1.el7 @xymon-testing
I DID change the config so that xymon is at the / of my web server, I'm not hosting anything else here. I'm relatively certain any client-side changes I've made aren't the problem since it works fine when on the main page. Any ideas how to fix this? I've spent a lot of time on this already and I just want to be done with it. :( Thanks in advance for any help, Signed,Extremely Frustrated (Jason Brockdorf)

Can you give us a snippet of your hosts.cfg?

Check the ghosts report. Maybe xymon isn't including them from the sub page because the syntax is wrong? If the client sends a report the server doesn't know about it is added to the ghost report.

No, they don't show up on the ghosts report. That was the trouble I had with the inconsistencies with names, the reason why I changed client to report short, lowercase hostname only.

I don't like the non-qualified domain names, but that shouldn't prevent this stuff from working. If you really are using short-names, I suggest putting an explicit TESTIP in your .default. line. Again, it shouldn't be the cause of your breakage, but it would be a good idea.

Have you tried this without the hypen in the page name?
group-only conn|cpu|memory|disk|info|ports|procs|sslcert|clientlog HTTP
re-using the group name should not cause any trouble.
if you run xymoncmd xymoncfg --web or xymoncmd xymoncfg --net
Is the hosts.cfg correctly parsed?
If you run xymoncmd xymonnet --no-update hhsce4aveimwst1 does the output look reasonable?
Is there anything interesting in xymond.log ?

Well, I figured it out. I uninstalled and reinstalled xymon server to see if using all stock would help and it didn't. All I added back into hosts.cfg was ONLY the IPs and hostnames with no page definitions. It was then either one of two things that I noticed (I didn't wait long enough between doing both of them to know which one fixed it...) First: I commented out the default #directory /etc/xymon/hosts.d line (because I noticed everything above was working and everything below was not) and then I noticed something else while waiting for it to update: In my history.log there was a bunch of lines: 2016-03-13 00:15:10.061160 Cannot create /var/lib/xymon/histlogs/someservername/cpu: File exists (someservername was one of the offenders) So I went and deleted everything in /var/lib/xymon/histlogs After that everything magically started to appear on the main page. I believe it was deleting the directories in histlogs that fixed it because they didn't all come back at once, they came back a few at a time (just as my winscp was deleting the directories serially instead of all at once) but that could be the client updates were coming in at different times as well *shrug*. I'm sure it was something I did wrong but it was extremely frustrating to say the least. Perhaps Xymon could try to append (is that appropriate for those files?) in such a situation instead of just logging an error and giving up? Thanks for all your help everyone that tried.
