Setting Memory Alarm Thresholds - HPE FlexFabric 5940 Series Configuration Manual

Setting memory alarm thresholds

To monitor memory usage, the device performs the following operations:
•
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 the amount of free memory space
exceeds a free-memory threshold, the system generates an alarm notification and sends it to
affected service modules or processes. If the amount of free memory space drops below a
free-memory threshold, the system generates an alarm-removed notification and sends it to
affected service modules or processes.
As shown in
•
Normal state threshold.
•
Minor alarm threshold.
•
Severe alarm threshold.
•
Critical alarm threshold.

Table 17 and Figure 32, 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.
