used memory capacity of the FreeBSD system is measured in days, and the diagram displays
the trend of the used memory capacity, and the maximum, minimize, and average value of
the used memory capacity. Move the pointer over the each sampling point to view the used
memory capacity of the FreeBSD system for the time being.
• Usage Ratio—Indicate the current memory (physical memory or swap memory) usage ratio of
the FreeBSD 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 FreeBSD system 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 FreeBSD system 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 FreeBSD system is measured in hours, and the diagram
displays the memory usage ratio trend, and the maximum, minimize, and average memory
usage ratio of the FreeBSD system; if you select the time period This year, the memory usage
ratio of the FreeBSD system is measured in days, and the diagram displays the memory usage
ratio trend, and the maximum, minimize, and average memory usage ratio of the FreeBSD
system. Move the pointer over the each sampling point to view the memory usage ratio of the
FreeBSD system for the time being.
Ping test
At the beginning of a host polling, APM starts a Ping test for the host that the FreeBSD 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 65.
