Custom non-ncv graph

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

I tried it with "VG2," but same.

When i had ncv VG graph,

SPLITNCV_VG="*:GAUGE"

i used

FNPATTERN VG.(.+).rrd
without problem and

-rw-rw-r-- 1 xymon xymon 19640 Mar 23 10:59
../data/rrd/hostname/VG,appvg.rrd
-rw-rw-r-- 1 xymon xymon 19640 Mar 23 11:00
../data/rrd/hostname/VG,rootvg.rrd
-rw-rw-r-- 1 xymon xymon 19640 Mar 23 11:00
../data/rrd/hostname/VG,vgdata.rrd

were created into one graph without problem.


[VG]
        FNPATTERN VG.(.+).rrd
        TITLE Volume group
        YAXIS Percentage
        DEF:p at RRDIDX@=@RRDFN@:lambda:AVERAGE
        LINE1.5:p at RRDIDX@#@COLOR@:@RRDPARAM@

        GPRINT:p at RRDIDX@:AVERAGE: \: %5.1lf (avg)\n

It produce
[*VG2*,appvg.rrd]

[*VG2*,rootvg.rrd]

I tried to define it also in graphs.cfg
[*VG2*]
        FNPATTERN VG2.(.+).rrd

Shouldn't that be:
          FNPATTERN VG2,(.+).rrd

I'm not entirely sure but I always thought the PCRE parser only looks
inside the parens, and so a dot (aka period, or ".") outside the parens
will be a literal dot, and won't match a comma in the filename.
