It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

This question, which shows a total lack of effort on your part, doesn't really deserve an answer. Nevertheless, try Googling for things like nagios, mrtg and "network monitoring". – John Gardeniers May 8 '12 at 7:56

Have a look at tools like Cacti which can request those performance metrics via snmp from your switches. We monitor our switches this way. Depending on the manufacturer of your switches there may be even more ways to solve your problem. Maybe your switches are capable to export NetFlow data?
