Class HeapMemoryUtilizationAlertConfiguration

java.lang.Object
  org.openspaces.admin.alert.config.HeapMemoryUtilizationAlertConfiguration

All Implemented Interfaces:

AlertConfiguration, BeanConfig

public class HeapMemoryUtilizationAlertConfiguration
extends Object
implements AlertConfiguration

A heap utilization alert configuration. Specifies the thresholds for triggering an alert. There are two thresholds, high and low and a measurement period indicating a window for the heap reading. The heap utilization alert is raised if any discovered JVM is above the specified heap threshold for a period of time. The heap utilization alert is resolved if its heap goes below the specified heap threshold for a period of time.

8.0

boolean	isEnabled()
void	setEnabled(boolean enabled)
void	setHighThresholdPerc(int highThreshold) Set the heap memory high threshold percentage value.
void	setLowThresholdPerc(int lowThreshold) Set the heap memory low threshold percentage value.
void	setMeasurementPeriod(long period, TimeUnit timeUnit) Set the period of time a heap memory alert should be triggered if it's reading is above/below the threshold setting.

LOW_THRESHOLD_PERC_KEY

public static final String LOW_THRESHOLD_PERC_KEY

Low threshold for which to resolve a previously triggered high heap memory alert. An alert will be triggered if heap memory goes below this threshold for a certain period of time.
