[Xymon] Graphing non-NCV data

[Stef Coene]

You can also send a trends message.
This is an extra message with the rrd you want to use and the numbers.
I use that feature a lot.

Some lines from one of my scripts written in perl:
   $rrd_return .= "data $ENV{MACHINE}.trends\n" ;
   $rrd_return .= "[iostat.$device.rrd]\n" ;
   $rrd_return .= "DS:Kbps:GAUGE:600:0:U $split[0]\n" ;
   $rrd_return .= "DS:tps:GAUGE:600:0:U $split[1]\n" ;
   $rrd_return .= "DS:bkread:GAUGE:600:0:U $split[2]\n" ;
   $rrd_return .= "DS:bkwrtn:GAUGE:600:0:U $split[3]\n" ;
