Ping Test
APM pings the host where the Windows performance counters are located at every polling interval. In a
ping test, APM sends out up to three ICMP packets to the host. When it receives a response, APM
considers the ping test a success and records the response time. When it receives no response after
sending out all ICMP packets, APM considers the ping test a failure. The Ping Test area layout is shown
in Figure 27.
