[rrd-users] Daily counter problem.

[Castricum, Ben]

Hi,
 
I tried to use rrdtool for monitoring an absolute value on a daily base. The
database is created with : 
 
${RRDTOOL} create counter.rrd \
   --step 86400 \
   --start 20020101 \
   DS:count:GAUGE:172800:0:U \
   RRA:AVERAGE:0:1:10000
 
A piece of data I entered in the database : 
 
1032559206:11246
1032645604:11246
1032732003:11246
1032818402:11265
1032904800:11276
1032991200:11280
1033077600:11290
1033164001:11301
1033250401:11301
1033336800:11301
etc..
 
But when I create a graph the values are much higher (about 10%) then they
should be. I think it has something to do with a timezone problem because a
dump of the database show 
 
                        <!-- 2002-09-21 02:00:00 CEST / 1032566400 -->
<row><v> 1.1246000000e+04 </v></row>
                        <!-- 2002-09-22 02:00:00 CEST / 1032652800 -->
<row><v> 1.1246000000e+04 </v></row>
                        <!-- 2002-09-23 02:00:00 CEST / 1032739200 -->
<row><v> 1.1247582674e+04 </v></row>
                        <!-- 2002-09-24 02:00:00 CEST / 1032825600 -->
<row><v> 1.1265916412e+04 </v></row>
                        <!-- 2002-09-25 02:00:00 CEST / 1032912000 -->
<row><v> 1.1276333333e+04 </v></row>
while the samples are taken at 0:00 (or a few secs later). Is there anyway I
can tell rrdtool use these values as how they are stored instead of
manipulating them first?
 
Thanks in advance,
Ben
