This tab defines configuration attributes for controlling WebLogic Server's automatic detection and correction of low memory conditions. Use these attributes to configure the frequency and granularity of low memory checks, as well as the threshold below which WebLogic Server logs low memory warnings.

Attribute Label	Description	Value Constraints
Low Memory GCThreshold	The threshold level (a percentage value) at which logs a low memory warning once the granularity reporting level has been met. MBean: weblogic.management. configuration.ServerMBean Attribute: LowMemoryGCThreshold	Minimum: 0 Maximum: 99 Default: 5 Configurable: yes Readable: yes Writable: yes
Low Memory Granularity Level	The granularity level used in reporting LowMemory information. MBean: weblogic.management. configuration.ServerMBean Attribute: LowMemoryGranularityLevel	Minimum: 1 Maximum: 100 Default: 5 Configurable: yes Readable: yes Writable: yes
Low Memory Sample Size	The total sample size used for LowMemoryTimeInterval. By default '10' samples are taken at each LowMemoryTimeInterval. MBean: weblogic.management. configuration.ServerMBean Attribute: LowMemorySampleSize	Minimum: 1 Maximum: 2147483647 Default: 10 Configurable: yes Readable: yes Writable: yes
Low Memory Time Interval	The time interval. So every configured 'time', one sample will be taken up to the LowMemorySampleSize and then repeated. MBean: weblogic.management. configuration.ServerMBean Attribute: LowMemoryTimeInterval	Units: seconds Minimum: 1 Maximum: 2147483647 Default: 3600 Configurable: yes Readable: yes Writable: yes
