We recently prepared a new FAQ document for our OpenResty XRay product on our website:

https://openresty.com/en/xray/faq/

It summaries true frequently-asked questions from our users over the years.

The FAQ focuses on hands-on usage questions. For a structured overview of what the product does across languages and runtimes, see Introduction to OpenResty XRay. And the question we hear most often — how does it actually find the culprit? — is answered in Automated Root Cause Analysis: How OpenResty XRay Pinpoints Failures Down to the Code Line.

If you have even more questions, feel free to contact us by sending emails to info@openresty.com. Thank you!
