Constructor Detail

DistributedLatencyCollectionResource

public DistributedLatencyCollectionResource(String locationMonitorId,
                                            String ipAddress)

Method Detail

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.

Specified by:

getInstance in interface CollectionResource

Returns:

a String object.

getUnmodifiedInstance

public String getUnmodifiedInstance()

Description copied from interface: CollectionResource

Returns the unmodified instance string this CollectionResource represents.

Specified by:

getUnmodifiedInstance in interface CollectionResource

Returns:

a String object.

getInterfaceLabel

public String getInterfaceLabel()

Description copied from interface: CollectionResource

Returns a unique label for each resource depending on resource type. This label is the same label used when constructing the resource ID.

Specified by:

getInterfaceLabel in interface CollectionResource

Returns:

a String object.

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

Specified by:

getResourceTypeName in interface CollectionResource

Returns:

a String object.

rescanNeeded

public boolean rescanNeeded()

Description copied from interface: CollectionResource

rescanNeeded

Specified by:

rescanNeeded in interface CollectionResource

Returns:

a boolean.

shouldPersist

public boolean shouldPersist(ServiceParameters params)

Description copied from interface: Persistable

Determines whether the attribute should be persisted.

Specified by:

shouldPersist in interface Persistable

Parameters:

params - a ServiceParameters object.

Returns:

a boolean.

addAttribute

public void addAttribute(CollectionAttribute attr)

Adds the given attribute into the collection for this resource

Parameters:

attr - The Attribute to add

getGroup

public final AttributeGroup getGroup(AttributeGroupType groupType)

Finds, or creates, and returns the AttributeGroup for the given group Type

Parameters:

groupType - a AttributeGroupType object.

Returns:

a AttributeGroup object.

visit

public void visit(CollectionSetVisitor visitor)

Description copied from interface: CollectionVisitable

Provide a way to visit all the values in the CollectionSet, for any appropriate purposes (persisting, thresholding, or others) The expectation is that calling this method will ultimately call visitResource, visitGroup and visitAttribute (as appropriate)

Specified by:

visit in interface CollectionVisitable

Parameters:

visitor - a CollectionSetVisitor object.

getOwnerName

public String getOwnerName()

Description copied from interface: ResourceIdentifier

getOwnerName

Specified by:

getOwnerName in interface ResourceIdentifier

Returns:

a String object.

getPath

public ResourcePath getPath()

Description copied from interface: ResourceIdentifier

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

Specified by:

getPath in interface ResourceIdentifier

Returns:

ResourcePath object.

toString

public String toString()

Overrides:

toString in class Object

getParent

public ResourcePath getParent()

Description copied from interface: CollectionResource

Returns the name of the parent resource.

Specified by:

getParent in interface CollectionResource

Returns:

a String 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

Returns:

a TimeKeeper object or null to indicate that DefaultTimeKeeper should be used.

getLocationMonitorId

public String getLocationMonitorId()

getIpAddress

public String getIpAddress()
