logging all connections on MT

Is there any chance to save logs from all connections on Mikrotik Router?
We tried to use Packet Sniffer but there is to many data (about 80mb/s) and router can’t hold this (checked “only headers”)

I would like to have txt file with:

Time of connection, wich IP connecting to other IP, what kind of connection (TCP or UDP) and PORT.

If someone have some idea please for help.

Best regards
