Now you can set Apdex thresholds when using htmlReporter through its apdexThresholds and transactionApdexThresholds methods. Thanks to @MaksSieve for the contribution!
Additionally, OctoPerfEngine has been refactor to avoid using jtl files for getting executions statistics, since they are heavy and they can even be incomplete (due to OctoPerf disk size limitation). Thanks to OctoPerf team for taking time to review OctoPerfEngine and pointing out different points of improvement!
