Suddenly all interface graph are blank as shown below, but aggregate traffic interface still display.
When i check RRDTools it shown empty. Anyone have any idea why its happen?

The RRDtool test doesn't show any rrd files. Did the interface graph template loose all it's data sources ?

Check the graph template for any issues.
