Before you get started 
The steps below should be followed when you experience performance issues with Salesforce and only when instructed by a Technical Support Engineer. The steps below might be slightly different based on the version of FiddlerCap you are using. For specific questions about how to use this software, please contact FiddlerCap Support.


To do this, we will use a tool, called Fiddler (by Telerik) (Not a Salesforce product). Fiddler is a tool for analyzing HTTP and HTTPS (must be enabled from within the app) transactions. This program is a simple-to-use version which can save logs which you can send back to the support team.

In order to install this program, you will need Administrative rights on your local machine. Please consult your IT department if you are unsure, or experience problems installing the application.

If you're working with a Salesforce support agent , they can request a capture  of network traffic to help with troubleshooting. These can be helpful for support to diagnose issues such as network performance, proxy and browser issues, Single Sign-on, or Integration troubleshooting.

1. Download Fiddler from Telerik to the local machine
2. Complete the installation and run the application
3. In Fiddler, from the top menu click on Tools | Options | HTTPS |Capture HTTPS CONNECTs
4. Check the box for Decrypt HTTPS traffic and agree to any prompts to install the needed certificate for https decryption
5. Select "Ignore Server Certificate errors" and click on ok to exit out of the Fiddler options.
6. Ensure Capture traffic is selected under the File menu or press F12
7. On Windows machines the WinConfig AppContainer Loopback Exemption Utility needs to be configured at least for Desktop App Web View and Office apps.

To do this if the prompt is not accepted at startup in Fiddler select the WinConfig button and load the "WinConfig AppContainer Loopback Exemption Utility"  here select "Exempt All" and "Save Changes"

8. Run the application or processes that needs debugging and do regular work until the issue seems to have re-occurred.
9. In Fiddler navigate to File | Save | All sessions and save them as a .saz file
10. Close Fiddler
11. Compress and zip the file and attach to the support case along with the information the exact time the issue occurred. You can also email it directly to the support rep you are working with. 

* To compress the file, locate the file in the folder after you saved it and then right click on it and click on Send to | Compressed (Zipped) folder
