point. Operators can view the memory usage statistics over the last 1 hour, last 6 hours,
today, yesterday, this week, this month, and this year by clicking the corresponding icons on
the upper right of the graph. The data shown in the line charts of last 1 hour, last 6 hours, and
today is collected in polling intervals. The data shown in the line charts of yesterday, this
week, and this month is collected in hours. The statistical results include the maximum,
minimum, and average values. The data shown in the line chart of this year is collected in
days. The statistical results include the maximum, minimum, and average values.
• Usage Ratio—Physical and virtual memory usage ratio.
 Set Threshold icon —Click the Set Threshold icon to set alarm thresholds for the
memory (including the physical and swap) usage ratio. The specified alarm thresholds appear

when the memory usage ratio reaches the level-1 threshold, and is highlighted in red when
the memory usage ratio reaches the level-2 threshold. You can either use the global thresholds
or self-defined thresholds.

Ping Test
When the polling interval expires, APM pings the Linux host by sending an ICMP packet. If a response
packet is received, the ping succeeds and APM records the response time. If no response packet is
received, APM sends another ICMP packet to the host. A maximum of three ICMP packets can be sent.
The Ping Test area layout is shown in Figure 115.
