[Xymon] Custom non-ncv graph

[Tomáš Wachtarczyk]

I am able to generate graph manualy by

rrdtool graph /tmp/output.png --width 500 --start 1458648243 -v "VG"  \
DEF:vgsize=/tmp/VG2,appvg.rrd:vgsize:AVERAGE \
DEF:vgfree=/tmp/VG2,appvg.rrd:vgfree:AVERAGE \
DEF:vgprct=/tmp/VG2,appvg.rrd:vgprct:AVERAGE \
LINE2:vgsize#FF0000:vgsize \
LINE2:vgfree#00FF00:vgfree \
LINE2:vgprct#0000FF:vgprct


So i think i have something wrong in graphs.cfg
