Element Description
Maintain Memory Log The number of hours that the router should maintain the log containing the
history of memory consumption on the device. Valid values range from 12 to
72 hours. The default is 24 (1 day).
Note The memory log is enabled by default and cannot be disabled.
Processor Threshold The processor memory threshold in kilobytes. When available processor
memory falls below this threshold, a notification message is triggered. Valid
values range from 1 to 4294967295 kilobytes (4096 gigabytes).
Note Another notification message is generated when available free
memory rises to 5% above the threshold.
I/O Threshold The I/O memory threshold in kilobytes. When available processor memory
falls below this threshold, a notification message is triggered. Valid values
range from 1 to 4294967295 kilobytes (4096 gigabytes).
Note Another notification message is generated when available free
memory rises to 5% above the threshold.
Memory Allocation
Lite
When selected, the “memory-allocation lite” (malloc_lite) feature on the
router is enabled. This feature avoids excessive memory allocation overhead
for situations where less than 128 bytes are required. This is the default.
When deselected, the “memory-allocation lite” feature is disabled.
Note This feature is supported for processor memory pools only.
Memory Region For
Critical Notifications
The amount of memory (in kilobytes) reserved for critical system log
messages. Valid values range from 1 to 4294967295 kilobytes (4096
gigabytes), but the value you specify cannot exceed 25% of total memory.
This option reserves a region of memory on the router so that the router can
issue critical system log messages even when system resources are
overloaded.
