Why is Azure Redis Enterprise Connection Event Auditing not working?

Shaun Wallace 20 Microsoft Employee

I have a Azure Redis Enterprise Cache, and I'm having issues where too many clients are concurrently and repeatedly connecting. I suspect the clients are not honoring a progressive backoff retry strategy. I am trying to enable Connection Event auditing in order to prove this assumption to the client.

In the azure portal I created a storage account in the same location and Resource Group as my Enterprise Redis Cache using all the default settings. In the Cache I created a "Diagnostic Settings - Auditing" policy to log connection events, and pointed it at my new storage account. But no logs are showing up in the storage account, even after multiple hours. Nor can Azure Monitor find any logs.

I suspect a permissions error, but do not know how to confirm or resolve. How can I investigate or resolve?

Hi @Shaun Wallace,

Thanks for the question and using MS Q&A platform.

Any destinations for the diagnostic setting must be created before you create the diagnostic settings. The destination doesn't have to be in the same subscription as the resource sending logs if the user who configures the setting has appropriate Azure role-based access control access to both subscriptions. By using Azure Lighthouse, it's also possible to have diagnostic settings sent to a workspace, storage account, or event hub in another Microsoft Entra tenant.

For more information, please refer: Destination limitations.

I hope this information helps, please let us know if you have any further queries.
