找不到Azure应用服务诊断日志应用程序日志记录Blob存储URL 404

Question

In my Azure App Service, I enabled Diagnostics Logs > Application Logging (Blob) and pointed to a Blob Storage Account. Like below.

And I also enabled Application Insight logging in the same App Service. But, in the application insight logging, I am seeing some error. It looks like below.

It seems, sometimes writing data from App Service to the Azure Blob Storage failed because it can't find the URL, hence it sends 404. The actual request / command showed in the image is:

https://myqalogs.blob.core.windows.net:443/my-qa-api-applogs/my-qa-api/2017/08/18/04/fc0efb-4524.applicationLog.csv?se=2037-08-16T11%3A32%3A01Z&sp=rwdl&sr=c&sv=2015-04-05&sig=QgSajcdke6PSzbqYizwJdCRuK2V37Jk2dA0v49hiBrs%3D&api-version=2014-02-14&comp=blocklist&blocklisttype=Committed

But, the content is there.

I am not sure where to check and how to solve these errors. Any help is highly appreciated.

Answer 1

I have also created a test demo on my side. I have reproduced this issue.

I guess this is related with how the azure Diagnostics logs works.

If the azure Diagnostics logs wants to log something to the azure blob.

It will firstly send a get request to get the blob file, then it will send a put request to put the logs to azure blob storage.

You could find the method the azure Diagnostics used is get not put.

So I think this will not affect your log details information just the azure Diagnostics logs check system.
