Running a Fiddler trace

Fiddler is a free third-party web debugging tool. Igloo Support may ask you to run a trace using this tool to better identify what may be causing unexpected behavior in your digital workplace. To create a trace, you will need to perform the action that is leading to your issue while Fiddler is running and recording.

Requirements for running Fiddler trace 

• Fiddler has been installed on your computer. For more information, see Install Fiddler.
• You have the appropriate level of Access to replicate the issue that Igloo Support is looking to collect a network trace of.

How to run a Fiddler trace

1. Exit and close all applications except for the ones that you are testing.
   • If you are collecting a trace for behavior in your digital workplace, close all browser tabs other than the one containing your digital workplace. 
   • This will help reduce the amount of noise that is captured by the network trace.
2. Launch Fiddler.
3. Configure Fiddler to decrypt HTTPS Traffic.
   • Tools > Options > HTTPS.
   • Decryption will be turned off after the trace is collected (step 10).
     
4. Restart Fiddler, and pause its capturing of network traffic.
   • Fiddler needs to be restarted for HTTPS decryption to take effect.
   • Pause Fiddler capturing by clicking the "Capturing" button on the bottom left-hand corner of Fiddler.
     
5. Prepare the situation that you want to capture a trace of.
6. Re-enable Fiddler's capturing of network traffic.
   • Click the "Capturing" button on the bottom left-hand corner of Fiddler.
7. Perform the action that you want a trace of.
8. Pause Fiddler's capturing of network traffic.
   • Click the "Capturing" button on the bottom left-hand corner of Fiddler.
9. Save the network trace.
   • File > Save > All Sessions
10. Remove Fiddler's ability to decrypt HTTPS Traffic.
    • Tools > Options > HTTPS.

Result of running a Fiddler trace.

After running the Fiddler trace you will have a copy of the network traffic that occurred. Send a copy of the network trace file, saved from step 9, to Igloo Support.
