KB2010011002 xn-Suite - xn-traff showing no data

Problem

xn-web interface is showing no traffic data for a vserver (xn-traff).

Reason and solution

xn-traff is able to start storing traffic data when the virtual network device counters reach 1 MByte ingoing or outgoing. You can check the current virtual network device counters of you vserver using the following command:

ifconfig eth0 | grep bytes

As that 1 MByte value is reached the traffic is beeing counted and stored every 5 minutes if in this time at least 1 KByte of traffic has been added ingoing or outgoing.
