Class NsclientMonitor
java.lang.Object
org.opennms.netmgt.poller.monitors.IPv4LatencyMonitor
org.opennms.netmgt.poller.monitors.NsclientMonitor
- All Implemented Interfaces:
- ServiceMonitor
- public class NsclientMonitor
- extends IPv4LatencyMonitor
This class is designed to be used by the service poller framework to test
the availability of a generic TCP service on remote interfaces. The class
implements the ServiceMonitor interface that allows it to be used along
with other plug-ins by the service poller framework.

NsclientMonitor
public NsclientMonitor()
poll
public int poll(NetworkInterface iface,
java.util.Map parameters,
Package pkg)
- Poll the specified address for service availability. During the poll an
attempt is made to connect on the specified port. If the connection
request is successful, the parameters are parsed and turned into
NsclientCheckParams
and a check is performed against the
remote NSClient service. If the NsclientManager
responds
with a NsclientPacket
containing a result code of
NsclientPacket.RES_STATE_OK
then we have determined that
we are talking to a valid service and we set the service status to
ServiceMonitor.SERVICE_AVAILABLE and return.
- Parameters:
parameters
- The package parameters (timeout, retry, etc...) to be used
for this poll.iface
- The network interface to test the service on.
- Returns:
- The availibility of the interface and if a transition event
should be supressed.
- Throws:
java.lang.RuntimeException
- Thrown if the interface experiences errors during the poll.
