Abstract: Embodiments provide contextualization for collecting performance metrics of various application components based on values of attributes of an incoming request (a calling context). This contextualization is not limited to the highest level of the application stack. Rather, this contextualization based on attributes' values of an incoming request can be carried down through the application stack and to hardware performing operations for processes in the application stack. In other words, performance metrics can be separated based on the calling context at different levels of the application stack. Accordingly, the calling context includes a value of at least one attribute of the incoming request and a path from a top of the application stack to a location of the application component being executed.

Abstract: In response to executing a first application component of a distributed application stack to process a first request to perform a first transaction received at a first device hosting the first application component and a second application component, operations are performed. The operations include determining a first context defining a first unique combination comprising a first value of an attribute of the first request and identification of a path of execution from a top of the distributed application stack to the first application component. The operations include assigning a first unique identifier to the first unique combination and monitoring a performance metric of the first application component to determine a first performance value of the first application component. The operations include adding the first performance value to a first accumulator value of a first accumulator that accumulates performance values for the first unique combination.

Abstract: The content and order of a predetermined sequence of hard-coded and/or quasi-programmable test patterns may be altered during a Built-In Self-Test (BIST) routine. As such, knowledge gained post design completion may be reflected in the selection and arrangement of available tests to be executed during a BIST routine. In one embodiment, a sequence of hard-coded and/or quasi-programmable tests is executed during a BIST routine by receiving test ordering information for the sequence of tests and executing the sequence of tests in an order indicated by the test ordering information. A corresponding BIST circuit comprises a storage element and a state machine. The storage element is configured to store test ordering information for the sequence of tests. The state machine is configured to execute the sequence of tests in an order indicated by the test ordering information.

Abstract: A technique for monitoring software which efficiently communicates transaction trace data, including static and dynamic data, from an agent to a manager. Corresponding tree data structures are maintained by the agent and manager which describe sequences of invoked components of a monitored application. The start and end of each component are each represented by a node in a branch of the tree data structure. To identify a transaction from a transaction trace, the agent can identify a matching branch, and communicate a unique identifier of the branch, such as an identifier of its last node, to a manager, with dynamic data such as start and end times of components. The manager looks up the sequences of invoked of components based on the identifier, and provides a display of the transaction trace. The trace can be annotated with static data indexed to the matching branch.

Abstract: Relationships between components in an application and the services they provide are identified, including redundant caller-callee sequences. Specific components of interest are instrumented to obtain data when they execute. Data structures are created which identify the components and their dependencies on one other. To avoid excessive overhead costs, redundant dependencies are identified. A dependency data structure can be provided for each unique dependency. When repeated instances of a dependency are detected, the associated dependency data structure can be augmented with correlation data of the repeated instances, such as transaction identifiers and sequence identifiers. Sequence identifiers identify an order in which a component is called. A flag can be used to force the creation of a new dependency data structure, and a calling component's name can be used instead of a sequence identifier. Agents report the dependency data structures to a manager to provide graph data in a user interface.

Abstract: A method and apparatus for displaying annotations on a digital image such that the viewing area is simplified and maximized. Abbreviated reason codes are employed, thereby increasing the number of annotations that may be displayed concurrently with an image and reducing the obtrusiveness of the annotations. The abbreviated reason codes may provide information to viewers about the significance of the image. Viewers may configure where the annotations are displayed and may associate priorities with the reason codes such that annotations of interest may be displayed more prominently or accessibly. Likewise, text descriptions associated with an annotation may be hidden until requested by a viewer. In instances where the number of annotations exceeds some configurable threshold, the excess annotations may be hidden unless requested.
