An indexing system provides a more efficient and effective interface to display and manipulate large amounts of trace data from computer data and storage networks that is captured and stored in the trace memory of a protocol analyzer. An index of the trace data in the trace memory is generated by reading a selected percentage of the trace data in the trace memory. Hardware circuitry selectively identifies locations in the trace memory of trace data for desired portions of the trace data. A proce...

Embodiments of the invention provide a method for determining errors and metrics in a computer network. The method includes positioning an analyzer in communication with the network, capturing a data trace of the network with the analyzer, determining a network device topology from a first processing of the data trace, building user layer protocols using a second processing of the data trace and the determined device topology, determining errors in the network device topology using protocol expe...

A method for analyzing transmitted protocol data units of a protocol for communication between two object request brokers to obtain a representation of messages included in the transmitted protocol data units includes collecting and correlating incomplete sets of information derived from the individual protocol data units for respective objects, and obtaining, from a plurality of necessary conditions, an adequate selection criterion for an interface definition to be used in a decoding operation....

A system and a method of automatically prioritizing and analyzing performance data for one or more system configurations are provided. Performance data is obtained about a system using a first tool. The performance data is sorted by a number of contexts, each context divided into a number of sub-contexts. The performance data for at least one sub-context is automatically prioritized using a pre-determined criteria. An insight is obtained using a second tool for at least one sub-context based on ...

Maintaining functionality during component failures is presented. During application registration, a recovery engine generates a recovery plan for the application. The recovery plan includes recovery actions that correspond to each component that the application intends to access. When an application encounters an unavailable component, the recovery engine provides a recovery action to the application which instructs the application how to proceed, such as accessing a backup component. The recov...

In one embodiment, a system and method for identifying incomplete transactions includes identifying termination of a test case run on a processor verification system, examining a pending transaction list to identify incomplete transactions, and examining at least one forward progress vector to identify incomplete transactions.

Some embodiments provide configuration of an internal monitoring mechanism of a processing device to output first data associated with a predetermined operational state of the processing device, and loading of control code into the processing device. The control code may be executable by the processing device to output second data associated with input operations and exceptions that occur during execution of test code by the processing device.

The trace logic are separate from the clocks that operate the system logic. This allows the chip to be placed in a special mode where the functional logic is issued one clock. One frame of trace data is generated for each functional clock issued. A valid signal may be implemented changing state when new information is generated. The trace logic, whose clock is free running, detects the change in state in the valid signal. It then processes the trace information presented to it, exporting this in...

The present inventions provides a method and apparatus for analyzing serial data. The invention comprises a serial analyzer which receives serial data from a logic analyzer. The serial analyzer processes the data to convert the serial data into parallel words. A listing tool receives the parallel words and generates a listing to be displayed. The listing generated is arranged in a first column and the sampled serial data is in a second column, so that, a user may view simultaneously the parallel...
