Method Detail

monitor

protected String monitor(Computer c)
                  throws IOException,
                         InterruptedException

Description copied from class: AbstractNodeMonitorDescriptor

Performs monitoring of the given computer object. This method is invoked periodically to perform the monitoring of the computer.

Specified by:

monitor in class AbstractNodeMonitorDescriptor<String>

Returns:

Application-specific value that represents the observed monitoring value on the given node. This value will be returned from the AbstractNodeMonitorDescriptor.get(Computer) method. If null is returned, it will be interpreted as "no observed value." This is convenient way of abandoning the observation on a particular computer, whereas IOException is useful for indicating a hard error that needs to be corrected.

Throws:

IOException

InterruptedException

getDisplayName

public String getDisplayName()

Description copied from class: Descriptor

Human readable name of this kind of configurable object.

Specified by:

getDisplayName in class Descriptor<NodeMonitor>

newInstance

public NodeMonitor newInstance(org.kohsuke.stapler.StaplerRequest req,
                               net.sf.json.JSONObject formData)
                        throws Descriptor.FormException

Description copied from class: Descriptor

Creates a configured instance from the submitted form.

Hudson only invokes this method when the user wants an instance of T. So there's no need to check that in the implementation.

Starting 1.206, the default implementation of this method does the following:

 req.bindJSON(clazz,formData);
 

... which performs the databinding on the constructor of Descriptor.clazz.

For some types of Describable, such as ListViewColumn, this method can be invoked with null request object for historical reason. Such design is considered broken, but due to the compatibility reasons we cannot fix it. Because of this, the default implementation gracefully handles null request, but the contract of the method still is "request is always non-null." Extension points that need to define the "default instance" semantics should define a descriptor subtype and add the no-arg newInstance method.

Overrides:

newInstance in class Descriptor<NodeMonitor>

Parameters:

req - Always non-null (see note above.) This object includes represents the entire submission.

formData - The JSON object that captures the configuration data for this Descriptor. See http://wiki.jenkins-ci.org/display/JENKINS/Structured+Form+Submission Always non-null.

Throws:

Descriptor.FormException - Signals a problem in the submitted form.
