The Status columns are showing graphs that are named like them, but you can 
only have one definition for "conn" so if you change this you must make sure 
to to not break the usual conn graph. e.g. by globbing with something like
`FNPATTERN (conn.*).tcp.rrd`.

In addition to this the GRAPHS variable contains a list of graphs showing up 
in the trends column. If you are referencing your definition there it will be 
available in the trends column.

The graph definitions are global at least at far I know. But you should be 
able to overload the names by adding them a second time. But be aware the 
definition is only searching for matching RRDs in /var/lib/xymon/rrd/
<XyHostname>/. That's why I mentioned the symlinks, in the directory of the 
main host in my previous mail. They are needed to get the data from the single 
hosts in there to glob for them.

Kind regards,
