Interface ServiceUsageMBean

public interface ServiceUsageMBean

The ServiceUsageMBean interface defines service usage-related management operations. Using a ServiceUsageMBean object a management client may get access to UsageMBean objects for SBBs, reset the usage parameters for an individual SBB used in the represented Service, reset usage parameters for all SBBs used in the represented Service, or modify the list of named usage parameter sets an SBB is allowed to use.

Each SBB maintains seperate sets of usage information for each Service that it participates in. A ServiceUsageMBean object provides management of usage information accumulated for a single Service for all the SBBs participating in that Service.

The base JMX Object Name of a ServiceUsageMBean object is specified by the BASE_OBJECT_NAME constant. The SERVICE_NAME_KEY, SERVICE_VENDOR_KEY, and SERVICE_VERSION_KEY constants define additional Object Name properties that uniquely identify a Service Usage MBean. The complete Object Name of a ServiceUsageMBean object can be obtained by a management client via the ServiceManagementMBean.getServiceUsageMBean(javax.slee.ServiceID) method.
