How to Check Utilization Percentage of an Interface

Hello! And thank you for reading! I'm very new to the world of Cisco Switches so I apologize if my question is dumb.

I was investigating packet drops on our switches for specific AV devices but I need to know the utilization percentage.

I am trying to figure out how to find Port Utilization of a specific Interface on my Cisco Switches. Or Utilization percentage, whichever way to word it.

Attached you will find a screenshot of one of my interfaces that I am trying to find the utilization of, I did show interface the specific port, to see.

Would it be the txload? I'm unsure of where to look.

I've done a few commands to see if I can decipher it but again, not sure if I am using the right ones.

I've done 'show controllers utilization'. Any guidance in finding utilization percentage would be great. Thank you!

"Would it be the txload?"

Yes, for transmission.  Yours is 58/255 = (about) 23% (over a five minute period)

As you only had 23 drops with 11,076,900,321 output packets, your drop percentage is nearly zero.  That, and with the small (for a gig interface) egress queue of 40 packets, means it's very, very unlikely the interface is adverse to your traffic.

BTW, interface utilization, especially over a five minute period can be very misleading and also especially when dealing with real-time traffic, which your AV might also comprise.
