We are using the Flow Statistics page in the NFA Administration GUI. Verified that port 8067 is open in both directions between the NFA Console machine and the Harvesters.
The graphs at the top of the page are showing data. When a Harvester is selected, a “Loading” indicator appears for over a minute, then a “No Matching records found” message appears.
The current Reporter\Logs\WebServicesQueryLog*.log shows the following timeout error:
11:13:57 -1 - Query:
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

By default, the Time Period for data in the Flow Statistics page is set to “Daily”. By shortening this Time Period, we can reduce the amount of data returned by the MySQL queries and reduce the possibility of Timeout errors.
