capacity. Move the pointer over the each sampling point to view the used memory capacity of
the Mac OS for the time being.
• Usage Ratio—Indicate the current memory (physical memory or swap memory) usage ratio of
the Mac OS system.
Formula: Usage Ratio=In Use/Total * 100%
 Threshold setting—Click the threshold setting icon to set the alarm threshold of
memory (physical memory or swap memory) usage ratio. The enabled threshold is shown in a
dotted line. The memory usage ratio is highlighted in yellow if the conditions of Level-1
threshold are met, and is highlighted in red if the conditions of Level-2 threshold are met. You
can set a user-defined threshold or a global threshold to control alarms of the memory usage
ratio.
 History Record—Click the History Record icon to view the memory usage ratio trend
of the Mac OS in a past time period, which includes the last 1 hour, last 6 hours, today,
yesterday, this week, this month, and this year. If you select the time period Last 1 hour,
Last 6 hours, or Today, the memory usage ratio of the Mac OS is measured in unit of a
polling interval; if you select the time period Yesterday, This week, or This month, the
memory usage ratio of the Mac OS is measured in hours, and the diagram displays the
memory usage ratio trend, and the maximum, minimize, and average memory usage ratio of
the Mac OS; if you select the time period This year, the memory usage ratio of the Mac OS
is measured in days, and the diagram displays the memory usage ratio trend, and the
maximum, minimize, and average memory usage ratio of the Mac OS. Move the pointer over
the each sampling point to view the memory usage ratio of the Mac OS for the time being.
Ping test
At the beginning of a host polling, APM starts a Ping test for the host that the Mac OS resides. During a
Ping test, APM sends ICMP packets to the host, and receives the response from the host. Once receiving
a response, which means that the Ping test is successful, APM records the time when receiving the
response. Otherwise, APM will try up to three times to Ping test the host.
The Ping Test pane is shown in Figure 77.
