How do I identify the cipher suite used to secure EUM beacon HTTPS connections?

When making a connection using HTTPS, either SSL or TLS encrypts the information being sent to and from the EUM server. The information is encrypted using a cipher or encryption key. The type of cipher depends on the cipher suite being used.


Use Google Chrome and the following steps to determine which cipher suite is used to secure the HTTPS connection with the EUM 'adrum' beacons. 


  1. Open Google Chrome and launch Chrome developer tools (ALT+CMD+I) by clicking on View > Developer > Developer Tools in the browser toolbar.

  2. Load your EUM-instrumented application in the browser.

  3. Click the 'Network' tab in Chrome developer tools and use the search bar to look for the beacon request named 'adrum'.

  4. Click on the request, then click the "Headers" tab on the right side of the screen.

  5. Copy the request URL. Example:
  6. Open a new window or tab in your browser and paste the request URL.

  7. Open Chrome developer tools in the new browser and click on the "Security" tab.

  8. Your cipher information is located under "Connection."

Is there a way we can check or extract this info into the EUM module?
