14. The method as set forth in claim 1 , wherein said at least one policy is applied for the purpose of measuring network latency using network metadata on said network. 15. The method as set forth in claim 14 , wherein said at least one policy includes the steps of: establishing a threshold time period during which a network device which requested services of a Domain Name Server (DNS) must receive a response from said DNS service; monitoring network metadata describing communications between network devices and DNS services; computing time elapsed between said network device request for a DNS service and receiving a response from that DNS service; comparing said elapsed time with said threshold time period; and generating an alert message to inform of excessive network latency.
