RrdPersistOperationBuilder

public RrdPersistOperationBuilder(RrdStrategy<?,?> rrdStrategy,
                                  RrdRepository repository,
                                  ResourceIdentifier resource,
                                  String rrdName,
                                  boolean dontReorderAttributes)

Method Detail

getRrdStrategy

public RrdStrategy<?,?> getRrdStrategy()

getRepository

public RrdRepository getRepository()

getRepository

Returns:

a RrdRepository object.

declareAttribute

public void declareAttribute(CollectionAttributeType attrType)

declareAttribute

Parameters:

attrType - a CollectionAttributeType object.

setAttributeValue

public void setAttributeValue(CollectionAttributeType attrType,
                              Number value)

setAttributeValue

Specified by:

setAttributeValue in interface PersistOperationBuilder

Parameters:

attrType - a CollectionAttributeType object.

value - a Number object.

setAttributeMetadata

public void setAttributeMetadata(String metricIdentifier,
                                 String name)

Specified by:

setAttributeMetadata in interface PersistOperationBuilder

mapType

public static RrdAttributeType mapType(AttributeType type)

Static method which takes a MIB object type (counter, counter32, octetstring, etc...) and returns the appropriate RRD data type. If the object type cannot be mapped to an RRD type, null is returned. RRD only supports integer data so MIB objects of type 'octetstring' are not supported.

Parameters:

type - - MIB object type to be mapped.

Returns:

RRD type string or NULL object type is not supported.

mapValue

public static String mapValue(Number num)

mapValue

public static String mapValue(Number num,
                              AttributeType type)

commit

public void commit()
            throws PersistException

commit

Specified by:

commit in interface PersistOperationBuilder

Throws:

PersistException - if any.

getName

public String getName()

getName

Specified by:

getName in interface PersistOperationBuilder

Returns:

a String object.

getTimeKeeper

public TimeKeeper getTimeKeeper()

getTimeKeeper

Returns:

a TimeKeeper object.

setTimeKeeper

public void setTimeKeeper(TimeKeeper timeKeeper)

setTimeKeeper

Parameters:

timeKeeper - a TimeKeeper object.
