Updated October 19, 2016

Overview

The NTA application shows no data in the charts. The collector shows the status as Up but no flows are showing up in the performance monitor making it into the NIC on the server. The following error is displayed in the Flow Storage Database logs:

ERROR FastbitCLR.BastbitTable - FastbitTable::AppendDataThread() Exception: Cannot create slot sync.

Environment

  • NPM 12.0
  • NTA 4.1.2

Cause 

This occurs when the Flow Storage Database is out of space.

Resolution

  1. Add more space to the Flow Storage Database drive. 
  2. Run the NTA Configurator.
