Dropped events not being logged in drop.log

I’m using the copy-mode: ips option of Suricata with two defined interfaces.

The suricata.log indicates that the First interface indicates there was 54509 (0.05%) of the packets dropped.

How do I record these packets? In the IDS Mode, dropped packets were easily logged.

Thank you.

They might not have been dropped due to signatures but other reasons like not enough resources, traffic spike etc.
