Package org.openspaces.admin.alert.config

Class HeapMemoryUtilizationAlertConfigurer

java.lang.Object

org.openspaces.admin.alert.config.HeapMemoryUtilizationAlertConfigurer

All Implemented Interfaces:

AlertConfigurer, BeanConfigurer<AlertConfiguration>

public class HeapMemoryUtilizationAlertConfigurer
extends Object
implements AlertConfigurer

A heap utilization alert configurer. 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.

Use the call to create() to create a fully initialized HeapMemoryUtilizationAlertConfiguration configuration.

HeapMemoryUtilizationAlertConfigurer

public HeapMemoryUtilizationAlertConfigurer()

Constructs an empty heap memory utilization alert configuration.

Method Details

enable

public HeapMemoryUtilizationAlertConfigurer enable(boolean enabled)

Description copied from interface: AlertConfigurer

Enable an alert using this configuration. By default an alert is disabled.

Specified by:

enable in interface AlertConfigurer

Parameters:

enabled - true to enable the alert using this configuration; false to disable the alert.

Returns:

this.

See Also:

• AlertConfiguration.setEnabled(boolean)

raiseAlertIfHeapAbove

public HeapMemoryUtilizationAlertConfigurer raiseAlertIfHeapAbove(int highThreshold)

Raise an alert if heap utilization if above the specified threshold for a period of time. The period of time is configured using measurementPeriod(long, TimeUnit).

Parameters:

highThreshold - high threshold percentage.

Returns:

this.

See Also:

• HeapMemoryUtilizationAlertConfiguration.setHighThresholdPerc(int)

resolveAlertIfHeapBelow

public HeapMemoryUtilizationAlertConfigurer resolveAlertIfHeapBelow(int lowThreshold)

Resolve the previously raised alert if heap utilization goes below the specified threshold for a period of time. The period of time is configured using measurementPeriod(long, TimeUnit).

Parameters:

lowThreshold - low threshold percentage.

Returns:

this.

See Also:

• HeapMemoryUtilizationAlertConfiguration.setLowThresholdPerc(int)

measurementPeriod

public HeapMemoryUtilizationAlertConfigurer measurementPeriod(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.

Parameters:

period - period of time.

timeUnit - the time unit of the specified period.

Returns:

this.

create

public HeapMemoryUtilizationAlertConfiguration create()

Get a fully configured heap memory utilization configuration (after all properties have been set).

Specified by:

create in interface BeanConfigurer<AlertConfiguration>

Returns:

a fully configured alert bean configuration.
