[rrd-users] Strange Data with 64bit Couters

[Reinartz, Ralf]

Hello,

I have a strange problem using rrd and 64Bit Interface Counters.

The interfaces are 2GBit Trunks with good load (around 30% i.e. 600 and more
MBit).

With code at the end of this Message I create and update the RRD Databases.

And now the Problem:

The values I get with rrd graph are higher than the bandwith.
Where is my misstake?

TIA

Ralf
