Monitor Interface Drops?

[sjnhawk]

This might be a newb question, but I was hoping that someone could shed some light on "Monitor Interface Drops" in Grafana. I recently had to change out a bad NIC on my standalone setup and am wondering if I took a hit on performance.

This is a fresh install of 2.3.220 and is running on a small network of around 30 devices. Unfortunately I did not record my previous stats, so I'm not sure if there is much of a delta there.

I'm averaging roughly 27-32 mp/s on Monitor Interface Drops, and am showing 0% packet loss for Zeek, Suricata, and Stenographer. Is this expected/within normal thresholds? Or is something not right?

I ran so-test and received the following results.

Sometimes Monitor Interface Drops are a symptom of an overwhelmed or misconfigured SPAN port or tap -- how are you getting data into your standalone?

I've got a SPAN port configured on a Unifi switch connected to my pfSense Firewall.
