Class ThresholdingVisitor

java.lang.Object
  org.opennms.netmgt.collectd.AbstractCollectionSetVisitor
      org.opennms.netmgt.threshd.ThresholdingVisitor

All Implemented Interfaces:

CollectionSetVisitor

public class ThresholdingVisitor
extends AbstractCollectionSetVisitor

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)

Method Detail

initThresholdsDao

protected static void initThresholdsDao()

handleThresholdConfigChanged

public static void handleThresholdConfigChanged()

createThresholdingVisitor

public static ThresholdingVisitor createThresholdingVisitor(int nodeId,
                                                            String hostAddress,

initThresholdState

public void initThresholdState()

Causes a new set of ThresholdEntity instances (i.e. threshold states) to be obtained for this visitor, at some appropraite point in the near future Can be called when thresholding configuration has changed and we need to refresh the threshold state

visitResource

public void visitResource(CollectionResource resource)

When called, we're starting a new resource. Clears out any stored attribute values from previous resource visits
