How to identify at what rate suricata is receving traffic?

Hi, I have a query - How would i know at what rate suricata is receving traffic from NIC ??
Suricata version - 6.0.14
OS - Ubuntu linux 20.04.5
Suricata installed using binary packages.

You can use the stats.log data for example the decoder.bytes which is updated based on the interval defined in the suricata.yaml so you could calculate that in post-processing. This might not include all packets but should be good enough. Otherwise use ethtool or /proc/net/dev to read the values from the NIC.
