What is a usage parameter?

A usage parameter is a parameter that an object in the SLEE can update, to provide usage information. There are two types:

  • Counter-type usage parameters have values that can be incremented or decremented.
  • Sample-type usage parameters accumulate sample data.

Accessing usage parameters

Administrators can access usage parameters through the SLEE's management interface.

Management clients can access usage parameters through the usage parameters interface declared in an SBB, resource adaptor or profile specification. Usage parameters cannot be created through the management interface. Instead, a usage parameters interface must be declared in the SLEE component. For example, an SBB declares an sbb-usage-parameters-interface element in the SBB deployment descriptor (similar procedures apply for resource adaptors and profile specifications).

You can also use notifications to output usage parameters to management clients.

Creating named usage parameter sets

By default, the SLEE creates unnamed usage parameter sets for a notification source. You can also create named usage parameter sets, for example to hold multiple values of usage parameters for the same notification source.
