[rrd-users] Where is the error

[Marc]

Where is the error?

Please have a lock to my code.

I am creating a rrd database, sending updates and generating a png.

The png is without dates and I cannot locate the error.

 

/usr/bin/rrdtool create /var/rrd/data/FA41E6010800.rrd \

After doing a dump, I can see that there are no dates in the database.
Having an empty png is Ok because ther are no datas, but why do I not get
the values into the database?

 

Regards

Marc
