Monitoring of unknown unicast traffic

Hello Team!

I would like to monitor unknown unicast storms in my network. Do you know any good way for that? What is the best practice?

Remark:

some days ago my two Juniper QFX switches (MC-LAG peers) stopped synchronizing MAC tables via ICCP -> one of the boxes started forwarding normal unicast traffic as unknown unicast -> servers connected to this switch began suffering from unknown unicast flood +20kpps + 200mbps (right now I am still trying to define the root cause of the issue with JTAC)
