Environment

9.3.8 and later.

Fixed in NFA 10.0.2.

Cause

In 9.3.8 and later if you have a router which is linked to two Harvesters and if one or more if its interfaces are included in a Flow Forensics report it can cause this error.

Resolution

This is fixed in 10.0.2, but in earlier versions you can run the script below on the NFA Console server to resolve this.

 

The script below will scan through your flow forensics report definitions for interfaces like this then as you if you want to delete the interface with the older timestamp which is likely no longer active.

 

Just unzip the file, right click and select "Run As Administrator" and follow the prompts.

Then restart the NetQos ReporterAnalyzer Report service and the NetQos ReporterAnalyzer Query service and try to run the Custom Reports again.
