Constructor Detail

SnmpTrapNorthbounder

public SnmpTrapNorthbounder(SnmpTrapNorthbounderConfigDao configDao,
                            String trapSink)

Instantiates a new SNMP Trap northbounder.

Parameters:

configDao - the SNMP Trap configuration DAO

trapSink - the trap sink

Method Detail

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Throws:

Exception

accepts

public boolean accepts(NorthboundAlarm alarm)

The abstraction makes a call here to determine if the alarm should be placed on the queue of alarms to be sent northerly.

Specified by:

accepts in class AbstractNorthbounder

Parameters:

alarm - the alarm

Returns:

true, if successful

isReady

public boolean isReady()

Description copied from interface: Northbounder

Used to determine if the northbounder is ready to accept alarms. If no northbounders are ready, the caller can save resources by not creating and initializing the NorthboundAlarms. This method is called once after northbounder is registered and started. If the status were to change sometime after, the northbounder must re-register itself.

Specified by:

isReady in interface Northbounder

Returns:

true if the northbounder is ready to accept alarms, false otherwise.

forwardAlarms

public void forwardAlarms(List<NorthboundAlarm> alarms)
                   throws NorthbounderException

Each implementation of the AbstractNorthbounder has a nice queue (Nagle's algorithmic) and the worker thread that processes the queue calls this method to send alarms to the northern NMS.

Specified by:

forwardAlarms in class AbstractNorthbounder

Parameters:

alarms - the alarms

Throws:

NorthbounderException - the northbounder exception

getConfig

public SnmpTrapNorthbounderConfig getConfig()

Gets the configuration.

Returns:

the configuration
