CopperEgg provides Website, Web service and TCP port checking from its 9 global monitoring stations, as frequently as every 15 seconds.  We refer to one ‘check’ as a Probe; you can define all aspects of each of your probes within the Probes tab in the CopperEgg UI.  Data gathered for each of your probes includes response time, health and copperegg.
