Ping Test

APM pings the Windows host 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 17.
