This invention relates to a diagnostic tool for networks that process messages in stages such as pipelined networks. In a pipelined network comprising tiers of servers, each tier of servers communicates only with adjacent tiers in a communications flow that processes messages in a sequence of tiers. The tool requires a controller located locally with respect to the pipelined network for generating messages to be processed by the pipelined network. Communication paths connect the controller to each tier of the pipelined network. A program executing at the controller detects a failure of the processing of the message by the pipelined network and receives diagnostic information from the tiers after the failure is detected. The diagnoses based on the retrieved information can proceed either manually or automatically, depending on how the information is collected. In order to automate the diagnosis, the program executing on the controller includes commands for sequentially analyzing each tier in the pipelined network in order to isolate the tier in which the failure occurred. For manual diagnosis, the program includes commands for simultaneously (or almost simultaneously) requesting information from each tier upon network failure. In the manual approach, distributed agents at all of the tiers gather information about the operating of the tier at the time of network failure.
A diagnostic tool in a pipelined network comprising tiers of servers wherein each tier of servers communicates only with adjacent tiers in a communications flow that processes messages in a sequence of the tiers, the tool comprising:
A method for diagnosing network failures in a pipelined server network comprising several tiers of processing a message, wherein each tier successively processes the message and forwards the message to the next tier, the method comprising:
A method for diagnosing failures in a pipelined network comprising processing tiers wherein each tier communicates only with adjacent tiers in a communications flow that proceeds sequentially from one tier to another, said method comprising:
A computer-readable medium, having computer-executable instructions for diagnosing network errors in a pipelined network comprising tiers of servers wherein each tier of servers communicates only with adjacent tiers in a communications flow that processes messages in a sequence of the tiers, the computer-executable instructions performing steps comprising:
