Intermittent Internet Slowdown

[powererum]

Hello. I am a network engineer working in an on-premises environment. There are intermittent slow internet issues, but it is not due to CPU or memory overload on the switch devices. When I monitored the situation using the diagnose switch physical-ports datarate command, I noticed a sudden increase in usage on both the TX and RX sides. What could be causing this issue? Also, are there other ways to check this in FortiGate or via CLI?
