Ping Test
When the polling interval expires, APM pings the Mac OS host by sending up to three ICMP packets.
When a response packet is received, the ping succeeds and APM records the response time. When it
receives no response after sending out all ICMP packets, APM considers that the ping test has failed. The
Ping Test area layout is shown in Figure 80.
