Class MonitorHealthVisualizer

Implemented Interfaces:
ChangeListener, Clearable, GraphListener, ImageVisualizer, ItemListener, JMeterGUIComponent, Printable, UnsharedComponent, Visualizer

public class MonitorHealthVisualizer
extends AbstractVisualizer
implements ImageVisualizer, ItemListener, GraphListener, Clearable

For performance reasons, I am using tabs for the visualizers. Since a visualizer is heavy weight, I don not want to have two separate result collectors rather the same information. Instead, I would rather have the visualizer be the container for the data and simply pass the data to child JComponents. In the future, we may want to add email alerts as a third tab.

Constructor Summary

MonitorHealthVisualizer()
Constructor for the GraphVisualizer object.

Method Summary

void
add(SampleResult res)
Because of the unique requirements of a monitor We have to handle the results differently than normal GUI components.
void
clearData()
Clears the MonitorAccumModel.
void
configure(TestElement el)
The GUI must be able to extract the data from the TestElement and update all GUI fields to represent those data.
Image
getImage()
String
getLabelResource()
Get the component's resource name, which getStaticLabel uses to derive the component's label in the local language.
void
itemStateChanged(ItemEvent e)
void
modifyTestElement(TestElement c)
GUI components are responsible for populating TestElements they create with the data currently held in the GUI components.

Constructor Details

MonitorHealthVisualizer

public MonitorHealthVisualizer()
Constructor for the GraphVisualizer object.

Method Details

add

public void add(SampleResult res)
Because of the unique requirements of a monitor We have to handle the results differently than normal GUI components. A monitor should be able to run for a very long time without eating up all the memory.
Specified by:
add in interface Visualizer

clearData

public void clearData()
Clears the MonitorAccumModel.
Specified by:
clearData in interface Clearable

configure

public void configure(TestElement el)
The GUI must be able to extract the data from the TestElement and update all GUI fields to represent those data. This method is called to allow JMeter to show the user the GUI that represents the test element's data.
Specified by:
configure in interface JMeterGUIComponent
Overrides:
configure in interface AbstractVisualizer
Parameters:

getImage

public Image getImage()
Specified by:
getImage in interface ImageVisualizer

getLabelResource

public String getLabelResource()
Get the component's resource name, which getStaticLabel uses to derive the component's label in the local language. The resource name is fixed, and does not vary with the selected language. Normally this method should be overriden in preference to overriding getStaticLabel(). However where the resource name is not available or required, getStaticLabel() may be overridden instead.
Specified by:
getLabelResource in interface JMeterGUIComponent
Returns:
the resource name

itemStateChanged

public void itemStateChanged(ItemEvent e)

modifyTestElement

public void modifyTestElement(TestElement c)
GUI components are responsible for populating TestElements they create with the data currently held in the GUI components. This method should overwrite whatever data is currently in the TestElement as it is called after a user has filled out the form elements in the gui with new information.
Specified by:
modifyTestElement in interface JMeterGUIComponent
Overrides:
modifyTestElement in interface AbstractVisualizer
Parameters:

updateGui

public void updateGui()
Specified by:
updateGui in interface GraphListener

updateGui

public void updateGui(Sample s)
Specified by:
updateGui in interface GraphListener
