ExtremeSwitching (EXOS)

I have summit x450, 460s. How often should one reboot these switches? What commands would you run on switch to tell if it needed a restart?

You shouldn't need to reboot them unless there's an upgrade or some problem you're trying to resolve.
What software version are they on, by chance?

15.7.2.9 on the 460's and 15.3.3.5 v1533b5-patch1-10 on the 450's.

Seems like a lot of random port congestion as well. Utilization is no
where near max line rate.
