Class Capsd

java.lang.Object
  org.opennms.netmgt.daemon.AbstractServiceDaemon
      org.opennms.netmgt.capsd.Capsd

All Implemented Interfaces:

Fiber, PausableFiber, SpringServiceDaemon, ServiceDaemon, org.springframework.beans.factory.InitializingBean

public class Capsd
extends AbstractServiceDaemon

The Capability daemon - it is notified by the discovery process when a new node is discovered - it then polls for all the capabilities for this node and is responsible for loading the data collecte1d into the database.

Once a node is added to the database, its sends an indication back to the discovery which then flags this node as 'known'.

getLocalHostAddress

public static String getLocalHostAddress()

Used to retrieve the local host name/address. The name/address of the machine on which Capsd is running.

scanSuspectInterface

public void scanSuspectInterface(String ifAddr)
                          throws UnknownHostException

This method is used by other managed beans to forward an IP Address for capability scanning. The If the interface converts properly then it is scanned as a suspect interface for the discovery of all the services and other interfaces that exists on the node.

Parameters:

ifAddr - The address of the suspect interface.

Throws:

UnknownHostException - Thrown if the address cannot be converted to aa proper internet address.

rescanInterfaceParent

public void rescanInterfaceParent(Integer nodeId)

This method is used to force an existing node to be capability rescanned. The main reason for its existence is as a hook for JMX managed beans to invoke forced rescans allowing the main rescan logic to remain in the capsd agent.

Parameters:

nodeId - The node identifier from the database.

setCapsdDbSyncer

public void setCapsdDbSyncer(CapsdDbSyncer capsdDbSyncer)

setSuspectEventProcessorFactory

public void setSuspectEventProcessorFactory(SuspectEventProcessorFactory eventProcessorFactory)

setCapsdConfig

public void setCapsdConfig(CapsdConfig capsdConfig)

setSuspectRunner

public void setSuspectRunner(RunnableConsumerThreadPool suspectRunner)

setRescanRunner

public void setRescanRunner(RunnableConsumerThreadPool rescanRunner)

setEventListener

public void setEventListener(StoppableEventListener eventListener)

setScheduler

public void setScheduler(org.opennms.netmgt.capsd.Scheduler scheduler)
