Class PhysicalMemoryUtilizationAlertConfigurer

java.lang.Object

org.openspaces.admin.alert.config.PhysicalMemoryUtilizationAlertConfigurer

All Implemented Interfaces:

AlertConfigurer, BeanConfigurer<AlertConfiguration>

public class PhysicalMemoryUtilizationAlertConfigurer
extends Object
implements AlertConfigurer

A physical memory 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 memory reading. The memory utilization alert is raised if any discovered machine is above the specified physical memory threshold for a period of time. The memory utilization alert is resolved if its physical memory reading goes below the specified memory threshold for a period of time.

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

Constructor Detail

PhysicalMemoryUtilizationAlertConfigurer

public PhysicalMemoryUtilizationAlertConfigurer()

Constructs an empty machine physical memory utilization alert configuration.

Method Detail

enable

public PhysicalMemoryUtilizationAlertConfigurer 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)

raiseAlertIfMemoryAbove

public PhysicalMemoryUtilizationAlertConfigurer raiseAlertIfMemoryAbove(int highThreshold)

Raise an alert if physical memory is 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:

PhysicalMemoryUtilizationAlertConfiguration.setHighThresholdPerc(int)

resolveAlertIfMemoryBelow

public PhysicalMemoryUtilizationAlertConfigurer resolveAlertIfMemoryBelow(int lowThreshold)

Resolve the previously raised alert if physical memory 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:

PhysicalMemoryUtilizationAlertConfiguration.setLowThresholdPerc(int)

measurementPeriod

public PhysicalMemoryUtilizationAlertConfigurer measurementPeriod(long period,
                                                                  TimeUnit timeUnit)

Set the period of time a physical 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 PhysicalMemoryUtilizationAlertConfiguration create()

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

Specified by:

create in interface BeanConfigurer<AlertConfiguration>

Returns:

a fully configured alert bean configuration.
