Field Reference

Table K-72	Memory Page
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		When selected, the “memory-allocation lite” (malloc_lite) feature on the
Lite		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		The amount of memory (in kilobytes) reserved for critical system log
Critical Notifications		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.
