We recommend enabling it by default for all customers in blackhole configuration with sFlow, Netflow or IPFIX telemetry enabled. It's not required for a port mirror as it has extremely fast detection speed already.
As usual, we offer free one month trial for FastNetMon Advanced which can be requested this way: https://fastnetmon.com/trial/
If you have any questions our sales team at sa...@fastnetmon.com will be happy to assist you.
