Class PhysicalMemoryUtilizationAlertConfigurer

java.lang.Object
  extended by 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.
