Method Detail

getServiceRef

public Ref getServiceRef()

Gets reference of service of which statistical information is available in this object.

Returns:

Service reference.

getCollectionTimestamp

public long getCollectionTimestamp()
                            throws java.lang.IllegalStateException

This method should be called after making sure that statistics are retrieved successfully. In case of statistics retrieval failure, collection time data will have no meaning and in such case this method will throw IllegalStateException.

Returns:

Collection timestamp in mSec.

Throws:

java.lang.IllegalStateException - If not collection timestamp is not set.

getAllResourceStatistics

public ResourceStatistic[] getAllResourceStatistics()
                                             throws InvalidServiceRefException,
                                                    MonitoringNotEnabledException,

Statistics for all resources of requested types. If statistics for one or more type of resources (that were specified in the operation which returned this object) are not present in the returned statistics, it means this service does not have any resources of those types.

Throws:

InvalidServiceRefException - If service reference is invalid or service is deleted.

MonitoringNotEnabledException - If statistics not found.

MonitoringException - If operation fails.

getResourceStatisticsByType

public ResourceStatistic[] getResourceStatisticsByType(ResourceType type)
                                                throws InvalidServiceRefException,
                                                       MonitoringNotEnabledException,

Parameters:

type - Resource type.

Returns:

Statistics for all resources of specified type. Null will be returned in following two situations: 1. This service doen not have any resource of the specified type. 2. Statistics for specified type were not requested in the operation that returned this object.

Throws:

InvalidServiceRefException - If service reference is invalid or service is deleted.

MonitoringNotEnabledException - If statistics not found.

MonitoringException - If operation fails.

public java.lang.String[] getMissingServers()
                                     throws java.lang.IllegalStateException

Returns array of missing servers. This method should be called after making sure that statistics are retrieved successfully. In case of statistics retrieval failure, missing server data will have no meaning and in such case this method will throw IllegalStateException.
