Hi Kern,

No worries. Lists are here to help.

I don't *believe* this will cause a problem within xymon, but hostnames 
with underscores can cause problems for some tools, even if it's allowed 
as a component of a DNS label.

Xymon will automatically create this symlink, although it's odd that 
it's in a distinct server root. Can you provide the WWW directory 
settings from within your xymonserver.cfg file?

This indicates that xymon is working okay (or, more specifically, that 
xymongen executed and was able to write these *.html files at least once).

You should be able to validate that xymond is running by looking at the 
output of 'ps axfww' on your machine.

This, combined with the ls listings above, would seem to indicate that 
there's some confusion on where xymon is configured to output its www 
files vs where the xymon.conf file in /etc/httpd/conf.d/ has the 
ServerRoot pointed to. Typically this is handled with an "Alias /xymon" 
line, but it can be configured wherever you'd like as long as the 
$XYMONSERVERWWWURL variable in xymonserver.cfg is set to the same.

I think all you may need to do is set XYMONWWWDIR=/var/www/html and 
XYMONSERVERWWWURL=/ in xymonserver.cfg and restart the service, assuming 
that you want xymon's display to live at the root of your web directory.

You'll also want to check the apache error logs for more details 
(they'll be in /var/log/httpd/).
