All on one line.

That should generate a graph for the root filesystem only. If you have
more filesystems - disk,*.rrd files - for this host, you can add an extra
"DEF:..." for each, just varying the "p1" to "p2", "p3" etc - and extra
"LINE:..." for each also.

If that fails, then you have a problem with rrdtool or the rrd-file is
corrupt.

If it works, then we have a problem with Xymon.
