Class TcaCollectionResource

java.lang.Object

org.opennms.netmgt.collection.support.AbstractCollectionResource

org.opennms.netmgt.collectd.tca.TcaCollectionResource

All Implemented Interfaces:

CollectionResource, CollectionVisitable, Persistable, ResourceIdentifier

public class TcaCollectionResource
extends AbstractCollectionResource

The Class TcaCollectionResource.

The resource type is fixed to juniperTcaEntry

This requires to define a datacollection-group like this:

 <datacollection-group name="Juniper TCA">
    <resourceType name="juniperTcaEntry" label="Juniper TCA Entry" resourceLabel="Peer ${index}">
     <persistenceSelectorStrategy class="org.opennms.netmgt.collection.support.PersistAllSelectorStrategy"/>
     <storageStrategy class="org.opennms.netmgt.collection.support.IndexStorageStrategy"/>
   </resourceType>
 </datacollection-group>
 

Note: the persistenceSelectorStrategy and storageStrategy won't be used by the collector.

Constructor Detail

TcaCollectionResource

protected TcaCollectionResource(CollectionAgent agent,
                                String peerAddress)

Instantiates a new TCA collection resource.

Parameters:

agent - the collection agent

peerAddress - the TCA peer address

Method Detail

getResourceTypeName

public String getResourceTypeName()

Description copied from interface: CollectionResource

Returns a string which indicates what type of resource. Will be one of "node" for the node level resource "if" for network interface resources "*" for all other resource types defined in the relevant config files, e.g. hrStorage

Returns:

a String object.

getInstance

public String getInstance()

Description copied from interface: CollectionResource

Returns the name of the instance this CollectionResource represents. For node level resources, this will be null to indicate the default instance. For interface level resources, some label unique to the node (ifIndex probably). For Generic resources (e.g. the SNMP GenericIndexResource), this will be some identifying label, probably the index in the table. This value is used by the StorageStrategy implementations to figure out the label for the resource which is used in constructing its RRD directory.

Returns:

a String object.

getInterfaceLabel

public String getInterfaceLabel()

Description copied from class: AbstractCollectionResource

getInterfaceLabel

Specified by:

getInterfaceLabel in interface CollectionResource

Overrides:

getInterfaceLabel in class AbstractCollectionResource

Returns:

a String object.

toString

public String toString()

Overrides:

toString in class Object

getPath

public Path getPath()

Description copied from class: AbstractCollectionResource

Retrieves path for the resource, relative to the root of the associated RrdRepository.

Specified by:

getPath in interface ResourceIdentifier

Overrides:

getPath in class AbstractCollectionResource

Returns:

Path object.

getTimeKeeper

public TimeKeeper getTimeKeeper()

Description copied from interface: CollectionResource

Returns a not-null TimeKeeper instance when this resource requires to use a special timestamp when updating RRDs/JRBs. If the resource doesn't need a special TimeKeeper it should return null.

Specified by:

getTimeKeeper in interface CollectionResource

Overrides:

getTimeKeeper in class AbstractCollectionResource

Returns:

Returns null to indicate that DefaultTimeKeeper should be used.

setTimeKeeper

public void setTimeKeeper(TimeKeeper timeKeeper)

Sets the time keeper.

Parameters:

timeKeeper - the new time keeper

setAttributeValue

public void setAttributeValue(TcaCollectionAttributeType type,
                              String value)

Sets the attribute value.

Parameters:

type - the type

value - the value
