This has to do with how many data sources appear on each multi-line graph on the trends page. In the example of if_load, you don't want all of your NIC data sources to appear on the one graph, and so the "::1" says to put only one on each graph.
There's a bit of a description on this in the xymonserver.cfg file. But the ultimate documentation is the source code, specifically xymonrrd.c. This indicates that the default lines per graph is 5. Also, between the two colons you can define "xymonpartname", but I can't work out where or how this is used.

Hi list,
I am currently struggling to find more detailed documentation on the GRAPHS setting in xymonserver.cfg. The manpage (or http://www.xymon.com/xymon/help/manpages/man5/xymonserver.cfg.5.html) is pretty sparse on that as I am curious what the effects of the "::1" suffixes are that are appended to some of the items, e.g. "if_load::1". I would appreciate any hints.
Thanks in advance -cs
