For details about the newer simulation overview, see Review simulation results for auto-labeling policies. Sample items, when displayed, shows the sampled item count. Contextual summary is available in supported portal experiences; viewing matched content requires the Data Classification Content Viewer role.
If simulation shows a failure message or counts marked (partial), see Failed simulations and partial results and simulation failure troubleshooting. Unavailable workload results aren't zero-match results, and restarting simulation doesn't guarantee that an error is resolved.
Finally, you can use simulation mode to provide an approximation of the time needed to run your auto-labeling policy, to help you plan and schedule when to run it without simulation mode.
