Blob Container not writing to $logs

Question

I have logging enabled for my blob storage, but no activity is logged. For the last few days, no new folders have been created in the $logs directory.

Answer 1

@Ryan Lee Thanks for posting your query on Microsoft Q&A.

Do you know the exact date since you stopped seeing the logs?
It could be because the classic diagnostic settings for Azure storage accounts are being phased out. Microsoft has announced that classic storage accounts and their associated diagnostics are being retired by August 31, 2024.

Here are the steps to complete the migration from classic Azure storage analytics to Azure Monitor metrics:

1. Identify Classic Storage Accounts: Check the Diagnostic settings (classic) for each storage account. If set to ON, the storage account is using classic Azure storage analytics
2. Enable Diagnostic Settings for Each Resource Type: On the storage account blade, ensure that diagnostics settings are enabled for blob, file, queue, etc., and configure them to send data to the new Log Analytics workspace
3. Disable Diagnostic Settings (Classic): Set the Diagnostic settings (classic) to OFF

Retain Logs: Ensure that the Delete data checkbox is selected and set the number of days for log data retention
