Abstract
A method and mechanism for configuring a node in a computing system to route data to a predetermined observation point. A node in a computing device or system is configured to identify and convey an observation data stream via a non-critical path. A non-critical path is configured within the computer system for the transmission of the generated stream of data to a convenient client location where the data may be observed. This stream of data is routed through the computer system via disabled, replicated, monitor or other links which correspond to a non-critical path. The observation data stream conveyed by the node may be generated by the node and correspond to an internal state of the node. Additionally, the node may be configured to duplicate and convey received data streams or extract debug data from a received data stream for conveyance to a predetermined observation point. By setting up a series of routing streams through a system, a circuit switched network may route observation data streams from any node in a system to any other node in the system.
