Samples memory usage at an interval of 1 minute, and compares the sample with the memory
•
usage threshold. If the sample is greater, the device sends a trap.
Monitors the amount of free memory space in real time. If a free-memory threshold is exceeded, the
•
system generates an alarm notification or an alarm-removed notification and sends it to affected
service modules or processes.
As shown in Table 15
• Normal state threshold.
Minor alarm threshold.
•
Severe alarm threshold.
•
• Critical alarm threshold.

and Figure 52, the system supports the following free-memory thresholds:
Triggering condition
The amount of free memory space
decreases to or below the minor
alarm threshold for the first time.
The amount of free memory space
decreases to or below the severe
alarm threshold for the first time.
The amount of free memory space
decreases to or below the critical
alarm threshold for the first time.
The amount of free memory space
increases to or above the severe
alarm threshold.
The amount of free memory space
increases to or above the minor
alarm threshold.
The amount of free memory space
increases to or above the normal
state threshold.

Remarks
After generating and sending a minor alarm
notification, the system does not generate
and send any additional minor alarm
notifications until the first minor alarm is
removed.
After generating and sending a severe alarm
notification, the system does not generate
and send any additional severe alarm
notifications until the first severe alarm is
removed.
After generating and sending a critical alarm
notification, the system does not generate
and send any additional critical alarm
notifications until the first critical alarm is
removed.
