Class MemorySampler

java.lang.Object
  atg.nucleus.logging.VariableArgumentApplicationLoggingImpl
      atg.nucleus.GenericService
          atg.service.statistics.MemorySampler

All Implemented Interfaces:

NameContextBindingListener, NameContextElement, NameResolver, AdminableService, ApplicationLogging, atg.nucleus.logging.ApplicationLoggingSender, atg.nucleus.logging.TraceApplicationLogging, atg.nucleus.logging.VariableArgumentApplicationLogging, ComponentNameResolver, Service, ServiceListener, SampleListener, java.util.EventListener

public class MemorySampler
extends GenericService
implements SampleListener

A MemorySampler obtains samples from a Sampler and stores them in memory for display through the administrative UI. The number of samples that can be stored is determined by the "sampleListSize" property.

MemorySampler

public MemorySampler()

Constructs a blank new MemorySampler

Method Detail

setSampleListSize

public void setSampleListSize(int pSampleListSize)

Sets the maximum number of samples that will be stored

getSampleListSize

public int getSampleListSize()

Returns the maximum number of samples that will be stored

getSampleCount

public int getSampleCount()

Returns the number of samples in the list

acceptSample

public void acceptSample(SampleEvent pSampleEvent)

This is called when a new SampleEvent is available

Specified by:

acceptSample in interface SampleListener

Parameters:

pSampleEvent - the sample list

doStartService

public void doStartService()

This will initialize the service

Overrides:

doStartService in class GenericService

createAdminServlet

protected javax.servlet.Servlet createAdminServlet()

Creates and returns a new Servlet that will administer this service. By default, this creates a ServiceAdminServlet, but subclasses may create their own servlets.
