Abstract
Augmenting a trace with at least one reverse lookup data structure during indexing of the trace. A method includes receiving trace data observed during execution of executable entit(ies), and replaying a plurality of different sections of the trace data. The replay includes, for each trace section, executing a plurality of code instructions of the executable entit(ies) based on the section's portion of the trace data, and recording attribute(s) observed during the execution of the code instructions along with an identity of the trace section. At least one reverse lookup data structure is created. It associates each of at least a subset of the attributes observed during the replay of the plurality of trace sections with the identity of each trace section in which it was observed. This reverse lookup data structure is stored as part of one or more trace data streams.
