If the configuration is set to have TotalView analyze more than the licensed number of interfaces, the Devices tab will only display the interfaces that are currently licensed. 

For example, if a license will permit monitoring 1,000 interfaces, then only the first 1,000 interfaces will be analyzed.

Additional interfaces beyond that 1,000 will not collect any health or performance statistics, but the device will still be listed.

To remedy this problem

  1. Purchase more licenses.
  2. Reduce the number of monitored interfaces by ignoring interfaces that don’t need to be monitored
  3. Remove devices from being monitored

Note: Ignoring or Removing devices that should be monitored will leave you blind to any issues that those ignored or removed devices have.
