The efficient monitoring of devices, applications, and services depends primarily on strategic placement of test engines. Your goal is to install Test Engines on hosts that are geographically representative of the enterprise’s users and sites. The physical location of NetIM is less significant.

Figure: Monitoring the enterprise’s devices and applications with Synthetic Testing shows all services and applications being served from the Northeast, plus test engines to represent users in both the Northwest and Southeast. Both test engines run periodic tests of the services that are important to users in their locations. All tests are monitored at a central location.
