Pb graphing a test with a varying set of data

[Vincent Schultz]

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@=@RRDFN@:lambda:AVERAGE
         LINE2:c at RRDIDX@#@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
