Package org.opennms.netmgt.threshd

Class ThresholdingVisitorImpl

java.lang.Object

org.opennms.netmgt.collection.support.AbstractCollectionSetVisitor

org.opennms.netmgt.threshd.ThresholdingVisitorImpl

All Implemented Interfaces:

CollectionSetVisitor, ThresholdingVisitor

public class ThresholdingVisitorImpl
extends AbstractCollectionSetVisitor
implements ThresholdingVisitor

Implements CollectionSetVisitor to implement thresholding. Works by simply recording all the attributes that come in via visitAttribute into an internal data structure, per resource, and then on "completeResource", does threshold checking against that in memory structure. Suggested usage is one per CollectableService; this object holds the current state of thresholds for this interface/service combination (so perhaps needs a better name than ThresholdingVisitor) Assumes and requires that the any visitation start at CollectionSet level, so that the collection timestamp can be recorded.

protected ThresholdingVisitorImpl(ThresholdingSetImpl thresholdingSet,
                                  ResourceStorageDao resourceStorageDao,
                                  ThresholdingEventProxy eventProxy,
                                  Long sequenceNumber)

Method Detail

setCounterReset

public void setCounterReset(boolean counterReset)

Specified by:

setCounterReset in interface ThresholdingVisitor

hasThresholds

public boolean hasThresholds()

Specified by:

hasThresholds in interface ThresholdingVisitor

Returns:

TRUE if there are defined thresholds for the node/address/service of the contained ThresholdingSet.

visitCollectionSet

public void visitCollectionSet(CollectionSet set)

Description copied from class: AbstractCollectionSetVisitor

visitCollectionSet

Specified by:

visitCollectionSet in interface CollectionSetVisitor

Overrides:

visitCollectionSet in class AbstractCollectionSetVisitor

Parameters:

set - a org.opennms.netmgt.collectd.CollectionSet object.

reload

public void reload()

Force reload thresholds configuration, and merge threshold states

Specified by:

reload in interface ThresholdingVisitor

reloadScheduledOutages

public void reloadScheduledOutages()
                            throws ThresholdInitializationException

Throws:

ThresholdInitializationException

isNodeInOutage

public boolean isNodeInOutage()

visitResource

public void visitResource(CollectionResource resource)

Description copied from class: AbstractCollectionSetVisitor

visitResource

Specified by:

visitResource in interface CollectionSetVisitor

Overrides:

visitResource in class AbstractCollectionSetVisitor

Parameters:

resource - a CollectionResource object.

visitAttribute

public void visitAttribute(CollectionAttribute attribute)

Add/Update required attributes for thresholds on m_attributeMap. This is used because CollectionResource does not have direct reference to their attributes. (The way to get attribute is against AttributeGroup object contained on CollectionResource implementations).

Specified by:

visitAttribute in interface CollectionSetVisitor

Overrides:

visitAttribute in class AbstractCollectionSetVisitor

Parameters:

attribute - a org.opennms.netmgt.collection.api.collectd.CollectionAttribute object.

completeResource

public void completeResource(CollectionResource resource)

Apply threshold for specific resource (and required attributes). Send thresholds events (if exists).

Specified by:

completeResource in interface CollectionSetVisitor

Overrides:

completeResource in class AbstractCollectionSetVisitor

Parameters:

resource - a CollectionResource object.

getCollectionTimestamp

public Date getCollectionTimestamp()

Description copied from interface: ThresholdingVisitor

Return the collection timestamp passed in at construct time. Used by integration test.

Specified by:

getCollectionTimestamp in interface ThresholdingVisitor

getEventProxy

public ThresholdingEventProxy getEventProxy()

setEventProxy

public void setEventProxy(ThresholdingEventProxy eventProxy)

toString

public String toString()

Overrides:

toString in class Object

getNodeId

public int getNodeId()
