What is JProfiler Origin Tracker?

"JProfiler Origin Tracker" is a Chrome extension designed for JVM profiling.

Extension summary

Analyze keywords

JProfiler is an all-purpose profiler for the Java virtual machine (JVM). As part of its CPU profiling capabilities, JProfiler can track execution from JavaScript code in the browser to a JVM that is handling XHR or fetch requests.

The call tree will be split for each separate JavaScript stack trace at the time of the XHR request and the full stack trace is available in the node detail dialog. A dedicated "JavaScript XHR" view shows the JavaScript call tree of all XHR calls that were handled in the profiled backend together with hyperlinks that take you to the execution site.

The extension adds a button to the toolbar for starting and stopping the XHR tracking.

How to use this after adding in Chrome, now able to find any report if we start recording the XHR

It works ok, but your extension produces the following erroneous error on opening any React.JS frontend site — `Unchecked runtime.lastError: The message port closed before a response was received [name of React file]:1.` this happens with your extension turned on, no matter what. For further info on this, see the Gatsby.JS (also based on React.JS) Issues log here — https://github.com/gatsbyjs/gatsby/issues/9899
