Resolution

NTA Flow Storage Database can process up to 300,000 flows per second. The load has to be distributed among multiple pollers, because one NTA poller is able to process a maximum of 50,000 flows per second. 

For more information, see the Scalability Engine Guidelines.

Applicable for NTA 4.4 and later:
You can get an idea of the average flows per second over a period of time in the dbo.NetflowEnginesStatistics table in the Orion Database.

Periods of Time displayed:

  • Flows per second for Last 24 hours
  • Flows per second for Last 3 days
  • Flows per second for Last 5 minutes

Each Engine will be displayed by the EngineID column in the database:



This will give you an idea how many flows per second on average you are collecting for these time periods. This will lead you to evaluate the consumption of data for each engine which can be totaled up per each time period. i.e.


Example:

(EngineID 1, Flows Per second for Last 24 hours, Statistic Value = 1000) + (EngineID 2 , Flows Per second for Last 24 hours, Statistic Value = 1000) = 2000 Flows Per second for Last 24 hours


*Please keep in mind this is the amount of flows consumed by the collector/engine. This has no bearing on the amount of flows sent to the Orion server which is very important to know as the engine may not be able to handle all the flows sent to it. See the following article to learn more about how to see how many flows are sent to the Orion server: Determine the NTA flows per second.
