Automatically Detecting Low Memory Conditions

Attributes

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
