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.
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.
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.
