Method Details

onOnline

public void onOnline(Computer c,
 TaskListener listener)
              throws IOException,
InterruptedException

Triggers the update with 5 seconds quiet period, to avoid triggering data check too often when multiple agents become online at about the same time.

Overrides:

onOnline in class ComputerListener

listener - This is connected to the launch log of the computer or Jenkins master. Since this method is called synchronously from the thread that launches a computer, if this method performs a time-consuming operation, this listener should be notified of the progress. This is also a good listener for reporting problems.

Throws:

IOException - Exceptions will be recorded to the listener. Note that throwing an exception doesn't put the computer offline.

InterruptedException - Exceptions will be recorded to the listener. Note that throwing an exception doesn't put the computer offline.

Description copied from class: ComputerListener
