Why it is impossible to access LogStream of a Managed Application App Service?

Question

We have a managed application published in Microsoft Partner Center, for preview audience.

We have both publisher and client tenants. After installing the app into the client's tenant I can't access the log steam of the installed app from either publisher / client tenants. When I'm trying to open Log Stream i can see only "connecting....".

Previously, as i have described here, we were able to access logstream using Visual Studio. However, Visual Studio log stream has stopped working as well.

We cannot access log stream at all!

Why this is happening and how can i access log stream of a Managed Application App Service?

Answer 1

I have referred the MSDoc which is provided in the Managed Applications in Azure Portal.

• I have created a managed Application using the ARM Template.

• Enable the App Service Logs and the required Level of Logging.

• Iam able to see the Logs from Log Stream.

how can i access log stream of a Managed Application App Service?

We can use Azure CLI command to check the Logs.

az webapp log tail --name YourAppName --resource-group RGName
