Final Update: Friday, 04 June 2021 19:05 UTC
We've confirmed that all systems are back to normal with no customer impact as of 6/4, 18:52 UTC. Our logs show the incident started on 05/28, 18:05 UTC.
Customers using Azure Functions may have been presented with the message, "Click ‘Add Diagnostic setting’ above to configure the collection of the following data" list of App Service Diagnostics logs when attempting to configure Function Apps to export data using the Diagnostics Preview blade. Customers may have been unable to configure export to Storage, Event Hubs, or Log Analytics for FuntionAppLogs. Existing Diagnostics settings would continue to work.
Root cause: A deployment from a dependent service that Azure Functions relies on was rolled out on 28 May 2021, had caused a configuration change causing configurations to Function Apps for export data using the Diagnostics Preview blade to experience issues.
Mitigation: We rolled out a hotfix to revert the configuration change, mitigating the issue.
We understand that customers rely on Application Insights as a critical service and apologize for any impact this incident caused.

We are aware of issues within Diagnostics Logs and are actively investigating. Customers that want to configure their Function Apps to export data using the Diagnostics Preview blade are unable to configure export to Storage, Event Hubs, or Log Analytics for FunctionAppLogs. Instead they see a list of App Service Diagnostics logs. Note that logs that are already configured will continue to work and this issue just affects users trying to configure new settings or adjust existing ones. This setting is in public preview.
