Claim 9:
10. A data bus analysis system, comprising:
one or more computer readable storage media; and
program instructions stored on the one or more computer readable storage media that, based on being read and executed by a processing system, direct the processing system to at least:
monitor first packets among traffic carried by one or more first directional lanes of a communication link established between a host having a root complex and one or more endpoint devices and determine header information for the first packets, wherein the communication link carries packets in a higher-level protocol over an underlying protocol and wherein the header information determined for the first packets comprises bus-device-function (BDF) properties;
detect second packets among traffic carried by one or more second directional lanes of the communication link based at least in part on the header information determined for the first packets; and
establish transaction metadata comprising properties of transactions on the communication link based at least on correlations among the first packets and the second packets, wherein the transaction metadata comprises transaction tags that organize individual transactions monitored on the communication link, associated endpoint addresses, transaction types, and the BDF properties.
