Constructor Detail

JMXDataSource

public JMXDataSource()

Constructor

JMXDataSource

public JMXDataSource(MibObject obj,
                     String collectionName)

JMXDataSource

public JMXDataSource(JMXDataSource second)

Class copy constructor. Constructs a new object that is an identical to the passed object, however no data is shared between the two objects. Any changes to one will not affect the other.

Parameters:

second - The object to make a duplicate of.

Method Detail

handlesType

public static boolean handlesType(String objectType)

Parameters:

objectType - MIB object type being inquired about

Returns:

true if RRDDataSource can handle the given type, false if it can't

mapType

public static String mapType(String objectType)

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:

objectType - - MIB object type to be mapped.

Returns:

RRD type string or NULL object type is not supported.

setOid

public void setOid(String oid)

This method is used to assign the object's identifier.

Parameters:

oid - - object identifier in dotted decimal notation (e.g., ".1.3.6.1.2.1.1.1")

setInstance

public void setInstance(String instance)

This method is used to assign the object's instance id.

Parameters:

instance - - instance identifier (to be appended to oid)

setName

public void setName(String name)

This method is used to assign the data source name.

Parameters:

alias - - object alias (e.g., "sysDescription")

getOid

public String getOid()

Returns the object's identifier.

Returns:

The object's identifier string.

getInstance

public String getInstance()

Returns the object's instance id.

Returns:

The object's instance id string.

getName

public String getName()

Returns the object's name.

Returns:

The object's name.

setType

public void setType(String type)

This method is used to assign the object's expected data type.

Parameters:

type - - object's data type

setHeartbeat

public void setHeartbeat(int heartbeat)

setMin

public void setMin(String minimum)

setMax

public void setMax(String maximum)

getType

public String getType()

Returns the object's data type.

Returns:

The object's data type

getHeartbeat

public int getHeartbeat()

getMin

public String getMin()

getMax

public String getMax()

clone

public Object clone()

Used to get a duplicate of self. The duplicate is identical to self but shares no common data.

Overrides:

clone in class Object

Returns:

A newly created copy of self.

toString

public String toString()

This method is responsible for returning a String object which represents the content of this RRDDataSource object. Primarily used for debugging purposes.

Overrides:

toString in class Object

Returns:

String which represents the content of this RRDDataSource object

performUpdate

public boolean performUpdate(String owner,
                             File repository,
                             SnmpValue value)

getStorableValue

public String getStorableValue(SnmpValue snmpVal)
