I've got the FibreAlliance-pluggin successfully running,
but unfortunately without trend/performanece data
[snip]
# Send performance data separately for better control
# trends rrdfile hostname data
Check if the .rrd-files have appeared in the ~xymon/data/rrd/HOSTNAME/ directory - if they have, then it's an issue of setting up graphs.cfg with the graph definitions, and updating the TEST2RRD and GRAPHS settings in xymonserver.cfg.
If there are no rrd-files, then your plugin-script has a problem.

Henrik
