Playback Ports:

While initial recording via the Recorder uses the standard HTTP/S ports on your local machine (ports 80 and 443), the default ports used for Recorder playback are:

  • IE Playback: 7777

  • FF Playback: 8100

  • CH Playback: 337


How to Modify:

These ports can be modified if needed, steps as followed:

  1. Close any open Recorder windows.

  2. Open the following file in a text editor:
    C:\Program Files (x86)\Dynatrace\Dynatrace Recorder\defaults\preferences\gsr.js

  3. Change the port value in the appropriate preference line for the Agent you want to modify:

    • IE Agent: pref("extensions.gsr.smallie.port",7777);
    • FF Agent: pref("extensions.gsr.gozilla.port",8100);
    • CH Agent: pref("extensions.gsr.webkit.port",337);
  4. Save the file and relaunch the Recorder.
