Setting NetStream Parameters

By adjusting NetStream parameters, you can ensure that statistics accurately reflect network status and avoid causing a great impact on the forwarding performance of the device.

Configuring NetStream Sampling: By lowering the sampling rate of NetStream, you can reduce the impact on the forwarding performance of the FW. However, raising the sampling rate improves the statistical accuracy.

Configuring the Aging Time for Flows: After the flow ages, the FW sends information to the NSC through UDP. You can adjust the active timeout and inactive timeout for flows.

Configuring Parameters for Refreshing the Template: Version 9 uses the template to output statistics. For example, by adjusting the parameters in the template, you can change the interval for sending the template.
