Method Detail

Override this method to define a custom monitor name. Defaults to the name of this class. The monitor key is the key for which the error message returned by check() is displayed.

The key for this monitor.

check

String check()
      throws Exception

This method is invoked each time the monitor is refreshed. In case the check was successful, this must return CHECK_SUCCESS. If the check was not successful, you have got the following options:

• Throw an Exception.
• Return an error message. This error message is shown by the monitoring MBean. You may return any arbitrary error message string, or use CHECK_ERROR. Make sure you do not return the value of CHECK_SUCCESS, as that is interpreted as a successful check.

Returns:

Whether the check was successful or not. To indicate success, return "success". Otherwise, return an appropriate error message.

Throws:

Exception - When the check was not successful. The error message is returned to the monitoring MBean.
