Core Performance Engineering Aviator service

Core Performance Engineering Aviator is a cloud-based enterprise service that delivers artificial intelligence (AI) capabilities for OpenText Performance Engineering products that are connected to this paid service.

Aviator provides scripting support through VuGen and automated AI-assisted analysis through Core Performance Engineering Analysis. For details on supported client instances and integrating with Aviator, see OpenText Core Performance Engineering Aviator in the OpenText Core Performance Engineering Help Center.

AI-driven scripting assistance

Aviator for Scripting in VuGen is generally available for all users. It provides assistance throughout the scripting process to save time and simplify script creation.

Aviator for Scripting includes the following key capabilities:

• Selecting protocols: Provides assistance on selecting the most appropriate protocol for creating a script.

• Providing coding support: Assists with performing specific tasks in VuGen.

• Analyzing errors: Helps identify and resolve script errors.

• Optimization: Reviews scripts and provides suggestions for improvement.

• Summarize: When a script is complete, Aviator can create a summary of key actions executed by the script.

When used together, these features save time and reduce the scripting skills required.

For details, see Aviator for Scripting in the OpenText Virtual User Generator Help Center.

AI-driven data analysis

Aviator for Analysis in Core Performance Engineering Analysis is generally available for all users. It includes the following key capabilities:

• Conversational analysis: Performance engineers can interact with Aviator using natural language, directly within the dashboard environment.

• Error analysis: Performance engineers can interact with the Aviator directly in the Error grid to request general error details, possible root causes, and recommended remediation steps.

• Widget generation: Performance engineers can generate dashboard widgets using natural language or predefined prompts.

MCP support is now available, providing a standardized and secure way to leverage AI-driven natural-language prompts to streamline and automate performance engineering workflows. This release includes the following MCP servers:

MCP server for Core/Enterprise/Professional Performance Engineering

An MCP server is available for each performance engineering solution, enabling you to run performance tests using natural language. For details, see the relevant Help Center.

MCP server for DevWeb

DevWeb now supports MCP. Using Microsoft Copilot in Visual Studio Code, you can use natural language to interact with the DevWeb MCP server and perform common tasks such as:

• Record a DevWeb script.

• Generate a DevWeb script from a HAR file.

• Generate a DevWeb script from a Swagger file.

• Run DevWeb scripts in Single mode, Single mode with iterations, or Load mode.

For details, see the OpenText Performance Engineering for Developers Help Center.

You can now control how elapsed time is shown (relative or absolute) for all graphs in a tab, without adjusting each graph individually. For details, see Manage dashboard tabs.

You can now adjust the time range while a widget is in Expand View, and edit widget titles directly on the dashboard. For details, see Enlarge a section of the graph and Edit widget title.

The following updates were made to monitors:

• Added support for streaming monitors from OpenText Core Performance Engineering.

• OpenText Core Performance Engineering Analysis now supports additional monitors.

For details, see System resources graphs.

Added support for streaming data from OpenText Core Performance Engineering for scripts running on Linux and Windows on-premises load generators.
