## Performance Engineering Aviator (Beta)

This release includes the launch of a new advanced, AI-powered, virtual assistant for OpenText Performance Engineering solutions.

Area | Enhancement
--- | ---
VuGen | Aviator for Scripting in VuGen provides assistance with many aspects of the scripting process. Using AI assistance before, during, and after the scripting process can help to save time and simplify script creation. Aviator can assist with tasks such as selecting the best protocol for an application scripting session, error analysis and remediation, function and coding assistance, script optimization, and script summarizing. When combined, these assisted actions can yield significant time savings, while also reducing required scripting skill sets. All users, from new to experienced performance engineers, will welcome Aviator's partnership in the scripting process. For details, see Aviator for Scripting in the VuGen Help Center.
Core Performance Engineering Analysis | Aviator for Analysis in OpenText Core Performance Engineering Analysis redefines how teams approach performance analysis. It helps accelerate investigations, increase productivity, and streamlines the onboarding of new team members. Through conversational analysis, performance engineers can interact with Aviator using natural language directly within the dashboard environment. When you ask for summaries, trends, anomalies, or detailed insights, Aviator delivers clear, contextual answers about critical metrics. By leveraging Aviator’s capabilities, teams can significantly reduce the time spent diagnosing errors, and move faster from detection to resolution with actionable guidance. For details, see OpenText Core Performance Engineering Analysis integration.

LLM | This release introduces a new large language model (LLM) protocol that enables you to create scripts for testing LLMs, such as OpenAI and Gemini.
TruClient 2.0 - Web | The following updates are included for TruClient 2.0 - Web scripts: You can convert TruClient 2.0 - Web scripts to Web - HTTP/HTML format. In the Runtime Settings > Log page, you can now specify the MIME types to log for the HTTP response body. This can reduce overhead that may impact performance. Search functionality added, enabling you to search for text in the current view or the whole script. You can also use the Go to button to jump to a specified step. Steps can be marked as optional, so that they are skipped if the target object is not found. You can save steps in the Steps box as favorites, and quickly access them from the Favorites tab.
TruClient - Web | The following updates are included for TruClient - Web scripts: TruClient scripts support Chromium browser version 137. In the Runtime Settings > Log page, you can now specify the MIME types to log for the HTTP response body. This can reduce overhead that may impact performance.
DevWeb | The following updates are included for DevWeb scripts: You can configure DNS resolution to be performed per Vuser. The obtained IP address is stored in the internal Vuser cache, and resolved again either when expired, or between iterations. Hits per IP statistics are included in the Replay Summary.
Oracle | The Oracle - 2 Tier protocol now supports record and replay on Oracle Database 23ai.
Web - HTTP/HTML | When using the Web Recorder Chrome extension, you can now set the recorder to capture HTTP authentication, or to record only requests and responses without the login page.
Java | You can now experiment and run Java Vusers with unsupported versions of Java. You can also enable the scripting engine to use an unsupported Java version when generating Java code.

OpenText™ Performance Engineering for Developers (LoadRunner Developer) includes the following enhancements. For details, see the What's new.

Area | Enhancement
--- | ---
Trace-level logs | When using trace-level logging, you can choose to include or exclude the HTTP headers and/or HTTP body from the log. This provides control over the amount of detail included in the log.
InfluxDB | Support added for InfluxDB 3 database.
Trend Report | You can now view a report comparing test runs of your script. The Trend Report enables you to compare results for different data types, in bar or line format.
DNS resolution per Vuser | You can configure DNS resolution to be performed per Vuser. The obtained IP address is stored in the internal Vuser cache according to the defined Time to Live (TTL) policy. It is resolved again either when expired, or between iterations.
Postman Collection | You can now use the Offline Script Generator to generate a DevWeb script from a Postman Collection file. (Beta)
Observability with OpenTelemetry | This release introduces an integration with OpenTelemetry, providing observability support. The integration enables you to push telemetry data to an OpenTelemetry Collector when replaying scripts. (Beta)
gRPC | This release includes the following improvements for gRPC protobuf code generation: Improved information for payload structure. A separate connect function for connecting to the server.
