Hello,

I think the most you can do on a L3 switch is check utilization for the last 72 hours, by using the command:

L3Switch#show processes cpu history

What OS?  IOS or IOS-XE?

Ok, we're playing "20 questions" are we? 

Ok, what is the exact firmware of the switch running on?

we need to know what is the version of code running and you have any NMS you can monitor

here is troubleshoot guide :

 - Besides other replies you may also look into CIsco Prime, a network management tool, which offers an easy performance dash-board for core switches (too). You will also get notified , if core uplinks get saturated , for instance.

On a side note, Cisco Prime is definitely good...but even the most basic 50 device license costs >$5,000. So it is not cheap...;)
