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 Detail

### MonitorHealthVisualizer

    public MonitorHealthVisualizer()

  Constructor for the GraphVisualizer object.

Method Detail

### configure

    public void configure(TestElement el)

  Description copied from class: `AbstractJMeterGuiComponent`
  A newly created gui component can be initialized with the contents of a Test Element object by calling this method. The component is responsible for querying the Test Element object for the relevant information to display in its GUI.

  AbstractJMeterGuiComponent provides a partial implementation of this method, setting the name of the component and its enabled status. Subclasses should override this method, performing their own configuration as needed, but also calling this super-implementation.

  Specified by:
    `configure` in interface `JMeterGUIComponent`
  Overrides:
    `configure` in class `AbstractVisualizer`
  Parameters:
    `el` - the TestElement to configure

### modifyTestElement

    public void modifyTestElement(TestElement c)

  Description copied from interface: `JMeterGUIComponent`
  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 class `AbstractVisualizer`
  Parameters:
    `c` - the TestElement to modify

### getLabelResource

    public String getLabelResource()

  Description copied from interface: `JMeterGUIComponent`
  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

### 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`

### getImage

    public Image getImage()

  Specified by:
    `getImage` in interface `ImageVisualizer`

### itemStateChanged

    public void itemStateChanged(ItemEvent e)

  Specified by:
    `itemStateChanged` in interface `ItemListener`

### updateGui

    public void updateGui()

  Specified by:
    `updateGui` in interface `GraphListener`

### updateGui

    public void updateGui(Sample s)

  Specified by:
    `updateGui` in interface `GraphListener`

### clearData

    public void clearData()

  Clears the MonitorAccumModel.

  Specified by:
    `clearData` in interface `Clearable`
