Zusammenfassung:An apparatus, including: a deterministic monitored device; an interconnect to communicatively couple the monitored device to a support circuit; a super queue to queue transactions between the monitored device and the support circuit, the super queue including an operational segment and a shadow segment; a debug data structure; and a system management agent to monitor transactions in the operational segment, log corresponding transaction identifiers in the shadow segment, and write debug data to the debug data structure, wherein the debug data are at least partly based on the corresponding transaction identifiers.
