Learn more about errors

You can use Aviator to learn more about errors by accessing the error definitions and error logs.

To use Aviator to troubleshoot errors:

1. In the Runs page, select a run to analyze.

2. Click the Errors tab, or access it directly from the Dashboard using the Errors Details link.

3. Click the Aviator button in the banner to ask about overall error patterns, such as:

   • “What are the most frequent errors in this run?”

   • “Summarize root causes for all errors.”

4. Alternatively, to investigate a specific error, click the Aviator icon next to an error in the log, and ask targeted questions like:

   • “What does error -26630 mean?”

   • “What caused this error in script X?”

Usage tips and example questions

The following are general tips for using Aviator and maximizing its benefits.

Tip	Details
Start with predefined prompts	Quickly discover powerful insights with one click. This is perfect for new users or common use cases. For details on using prompts, see Manage prompts.
Use natural language	No special syntax required; just ask your question in plain English. Example: "What caused the errors at peak load?"
Focus on a single question	Short, focused queries often get better results. Long questions are more likely to fail.
Try follow-up questions	Build on Aviator's answers. Example: “Which scripts were most affected?” or “When did it start?”.

The following are some example questions that you can ask.

Page	Subject / Request
Dashboard	Correlate metrics: "Correlate throughput with Vusers over time." Experiment with filters: Ask Aviator to filter by script, host, transaction, or error code. For example, “Identify HPS spikes on host A only."
Errors	Ask about error root causes: “Identify the key findings and the possible root causes for the most frequent errors in this test run." Drill into error patterns: “List common causes for -26630 errors.”

Manage prompts

You can edit, reuse and retry prompts using the following actions.

Action	Description
Edit last prompt	You can edit the last prompt sent without having to retype or reconstruct complex queries. Note: Editing is only available for the last message in each chat session and becomes accessible after a page refresh or navigation between tabs or pages. This feature is not supported for older prompts. Only the last edited prompt is retained; previous versions are not stored. Edited messages are not marked as edited.
Reuse a prompt	You can reuse any previously sent prompt in the same chat session by copying and pasting it into other contexts or chats.
