Pb graphing a test with a varying set of data

[Vincent Schultz <vschultz (at) cvf.fr>]

Hello All,

I am experiencing a strange problem with a test which has a varying set
of data (with NCV). On the graph, we can see other data like 01,02,03. 
You can see a picture here :

In the RRD directory, there are
-rw-r--r-- 1 hobbit hobbit  19552 2009-01-21 01:56 mpstat,01.rrd
-rw-r--r-- 1 hobbit hobbit  19552 2009-01-21 02:56 mpstat,02.rrd
-rw-r--r-- 1 hobbit hobbit  19552 2009-01-21 03:56 mpstat,03.rrd
...
-rw-r--r-- 1 hobbit hobbit  19552 2009-01-21 08:49 mpstat,cpu_user_1.rrd
-rw-r--r-- 1 hobbit hobbit  19552 2009-01-21 08:49 mpstat,cpu_user_2.rrd
-rw-r--r-- 1 hobbit hobbit  19552 2009-01-21 08:49 mpstat,cpu_user_3.rrd
...

My configuration is :

In hobbitserver.cfg :

GRAPHS="...,mpstat"
...
SPLITNCV_mpstat="*:GAUGE"

In hobbitgraph.cfg :

[mpstat]
        FNPATTERN mpstat,(.+).rrd
        TITLE mpstat
        YAXIS valeur
        DEF:c (at) RRDIDX@= (at) RRDFN@:lambda:AVERAGE
        LINE2:c (at) RRDIDX@# (at) COLOR@:@RRDPARAM@
        -l 0
        GPRINT:c (at) RRDIDX@:LAST: \: %5.1lf (cur)
        GPRINT:c (at) RRDIDX@:MAX: \: %5.1lf (max)
        GPRINT:c (at) RRDIDX@:MIN: \: %5.1lf (min)
        GPRINT:c (at) RRDIDX@:AVERAGE: \: %5.1lf (avg)\n


I don't understand why I ve got such extra data ...

Can someone help me or point me in the right direction ?

Thank you,

Vincent
