- All Implemented Interfaces:
public class WmiMonitor
- extends IPv4Monitor
This class is designed to be used by the service poller framework to test
the availability of WMI services on remote interfaces. The class
implements the IPv4Monitor interface that allows it to be used along
with other plug-ins by the service poller framework.

public PollStatus poll(MonitoredService svc,
This method is the heart of the plug-in monitor. Each time an interface
requires a check to be performed as defined by the scheduler the poll
method is invoked. The poll is passed the interface to check
By default when the status transition from up to down or vice versa the
framework will generate an event. Additionally, if the polling interval
changes due to an extended unavailability, the framework will generate an
additional down event. The plug-in can suppress the generation of the
default events by setting the suppress event bit in the returned integer.
Poll the specified address for service availability. During the poll an
attempt is made to connect the WMI agent on the specified host. If the
connection request is successful, the parameters are parsed and turned
WmiParams and a check is performed against the
remote WMI service. If the
WmiResult containing a result code of
WmiResult.RES_STATE_OK then we have determined that
we are talking to a valid service and we set the service status to
SERVICE_AVAILABLE and return.
