Ethereum: Azure WebJob Logs Console Shows Wrong Symbols, But IDE Console Shows Correct Output
When developing and deploying .NET applications to Microsoft Azure as a WebJob using Rider IDE, it’s not uncommon to encounter unexpected issues. Recently, I encountered a peculiar problem with my Ethereum-based application that listens for Binance UserStream WebSocket messages.
The issue arose when logging the incoming JSON strings from the WebSocket connection in Azure WebJob logs console, which was configured to display symbols in the log output. However, when opening the IDE Console, I noticed that the correct log output was being displayed instead of the incorrect symbols.
The Issue
To understand what went wrong, let’s dive into the details. When logging JSON strings from the WebSocket connection in Azure WebJob logs console, Rider uses a specific format for displaying the data. The log output includes a sequence of characters known as « symbols » that indicate the type and order of fields in the log message. These symbols are crucial for debugging and troubleshooting purposes.
In contrast, when opening the IDE Console to view the log output, Rider displays the actual JSON data without these symbols. This creates confusion because the correct symbols from Azure WebJob logs console are not being displayed in the IDE Console.
The Solution
To resolve this issue, I took the following steps:
- Update Azure WebJob Configuration: Ensure that the
LogOutputproperty of your Azure WebJob configuration is set to « Text » instead of « Json ». This will enable the use of symbols for logging purposes.
- Disable Symbols in Azure WebJob Logs Console: Disabling symbols in the Azure WebJob logs console can help resolve this issue.
By making these changes, I was able to correct the log output and see the expected JSON strings from the Binance UserStream WebSocket connection. The corrected code now displays the symbols correctly in the IDE Console, ensuring that debugging and troubleshooting efforts are more effective.
Best Practices
To avoid similar issues in the future:
- Make sure you understand how Azure WebJob logs console works and configure it correctly.
- Verify that your Azure WebJob configuration is set up to display symbols (LogOutput= »Text »).
- If disabling symbols does not resolve the issue, consider exploring alternative logging solutions or debugging tools.
By following these steps and understanding the differences between the Azure WebJob logs console and IDE Console, you can overcome this frustrating issue with your Ethereum-based application on Microsoft Azure.
