• 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.
The device supports the following free-memory thresholds:
{ Normal state threshold.
{ Minor alarm threshold.
{ Severe alarm threshold.
{ Critical alarm threshold.
Table 14 and Figure 38 show how the d
evice generates notifications based on the free-memory
thresholds.
Table 14 Memory alarm notifications and memory alarm-removed notifications
Notification Triggering condition Remarks
Minor alarm notification
The amount of free memory
space decreases to or below the
minor alarm threshold for the
first time.
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.
Severe alarm
notification
The amount of free memory
space decreases to or below the
severe alarm threshold for the
first time.
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.
Critical alarm
notification
The amount of free memory
space decreases to or below the
critical alarm threshold for the
first time.
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.
Critical alarm-removed
notification
The amount of free memory
space increases to or above the
severe alarm threshold.
N/A
Severe alarm-removed
notification
The amount of free memory
space increases to or above the
minor alarm threshold.
N/A
Minor alarm-removed
notification
The amount of free memory
space increases to or above the
normal state threshold.
