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.

    • MEASUREMENT_PERIOD_MILLISECONDS_KEY

      public static final String MEASUREMENT_PERIOD_MILLISECONDS_KEY
      Period of time (in milliseconds) the JVM heap memory is above/below a certain threshold to trigger an alert.

    • 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.
      See Also:

    • HIGH_THRESHOLD_PERC_KEY

      public static final String HIGH_THRESHOLD_PERC_KEY
      High threshold for which to trigger an alert which needs resolution. An alert will be triggered if heap memory goes above this threshold for a certain period of time.
