[Xymon] probleme with a graph

hy

i have write a script and i try to establish a graph.

i add in the *hobbitserver.cfg* the name of my script like this :

TEST2RRD="couchbase=ncv"

GRAPHS="couchbase"

NCV_couchbase="bytesread:GAUGE,bytes:GAUGE"

And in the *hobbitgraph.cfg***i add

[couchbase] TITLE Couchbase info YAXIS Bytes_read DEF:bytes_read=couchbase.rrd:bytes_read:AVERAGE DEF:bytes=couchbase.rrd:bytes:AVERAGE

     LINE2:bytesread#FF000000:Bytes_read
     LINE2:bytes#FF66FF:Bytes
     COMMENT:\n
     GPRINT:bytes_read:LAST:Bytes_read \: %5.1lf%s (cur)
     GPRINT:bytes_read:MAX: \: %5.1lf%s (max)
     GPRINT:bytes_read:MIN: \: %5.1lf%s (min)
     GPRINT:bytes_read:AVERAGE: \: %5.1lf%s (avg)\n

     GPRINT:bytes:LAST:bytes        \: %3.2lf (cur)
     GPRINT:bytes:MAX: \: %3.2lf (max)
     GPRINT:bytes:MIN: \: %3.2lf (min)
     GPRINT:bytes:AVERAGE: \: %3.2lf (avg)\n

When i execute the command *rrdtool dump couchbase.rrd *I get my information as you can see below

<version>0003</version> <step>300</step> <!-- Seconds --> <lastupdate>1359043008</lastupdate> <!-- 2013-01-24 15:56:48 GMT -->

     <ds>
             <name> bytes </name>
             <type> GAUGE </type>

<minimal_heartbeat>600</minimal_heartbeat> <min>NaN</min> <max>NaN</max>

             <!-- PDP Status -->
             <last_ds>119541874</last_ds>
             <value>0.0000000000e+00</value>
             <unknown_sec> 108 </unknown_sec>
     </ds>

• when i m going to watch in my console i didn't see any graph , just a link for Hourly graph, Daily graph etc... i dont understand i missed something ?
