Unable to Enable Application Logs for Linux Web App on Azure App Service

Jacob Hughes-Hallett 0

Details:

I am trying to enable application logging for my Django app running on a Linux-based Azure App Service. My app is set up with the following details:

Operating System: Linux
Runtime Stack: Python 3.12
App Service Plan: PremiumV2 (P1v2)
Deployment Provider: VSTSRM (Azure DevOps)

Despite updating the App Service settings to enable Application Logging (File System) and restarting the app, I am unable to see any real-time logs in the Log Stream. The log stream is connected, but no new logs are coming through, and I keep seeing messages like:

Logging is not enabled for this container. Please use https://aka.ms/linux-diagnostics to enable logging to see container logs here.

Steps I've Taken:

Enabled Application Logging (File System) from the App Service settings.
Modified the Django settings to configure logging in the settings.py file.
Restarted the app and tested various requests that should generate logs.
Verified that my role has sufficient permissions, but I'm still not seeing the full diagnostic logging options (e.g., log levels, detailed error messages).
The app is running fine in the normal browser, but in incognito mode, I get a 500 error on one specific page, and I need logs to troubleshoot.

Questions:

Why am I not able to see logs in the Log Stream even though I have enabled logging from the App Service settings?
Are there additional steps to configure logging for a Linux-based Azure Web App running Django?

Hi @Jacob Hughes-Hallett
Thanks for the question and using MS Q&A platform.
To enable application logging for a Linux-based Azure Web App running Django:

Enable Logging: Visit the Linux Diagnostics page.

Django Logging: Add this in settings.py:

pythonCopy codeLOGGING = { 'version': 1, 'handlers': { 'file': { 'class': 'logging.FileHandler', 'filename': '/home/LogFiles/django.log', }, }, 'loggers': { 'django': {'handlers': ['file'], 'level': 'DEBUG'}, }, }

Enable Logs: In the Azure portal, go to App Service Logs, enable Application Logging (Filesystem).

Use Log Stream: View logs via Log Stream.
Restart the app after changes. https://learn.microsoft.com/en-us/azure/app-service/troubleshoot-diagnostic-logs

I hope this information is helpful. If you have any further questions, please don't hesitate to reach out.
