Are Azure App Configuration values written to Log Analytics?

Question

Are Azure App Configuration values written to Log Analytics?

Bradley Cotier 20 Microsoft Employee

I would like to surface on a Grafana dashboard the times when an Azure App Configuration key/value pair was set to certain values. However, as far as I can tell the values are not written to logs. This kind of makes sense if the resource is thought of as similar to Key vault but I would like some official documentation that states this is the case, so as to be certain that I am not just missing something.

N.B. - I have set up a diagnostic settings resource on the App Config instance and enabled all logs.

Hello Bradley Cotier,

Based on the Azure App Configuration monitoring documentation, diagnostic logs capture resource operations and related metadata. The published log schema does not include configuration values among the logged fields.

You can refer to the following Microsoft documentation:

Monitor Azure App Configuration: https://learn.microsoft.com/azure/azure-app-configuration/monitor-app-configuration

Azure Monitor Logs reference for Azure App Configuration: https://learn.microsoft.com/azure/azure-monitor/reference/supported-logs/microsoft-appconfiguration-configurationstores-logs

While the documentation doesn't explicitly state whether configuration values are written to Log Analytics, the published log schema does not include configuration values among the logged fields.

If you need to show when a key was set to a specific value in Grafana, you'll need to implement your own auditing solution, such as logging the value changes from your application or deployment pipeline before updating Azure App Configuration.

I hope this helps. Please let us know if you have any further questions.

Hi @Bradley Cotier ,

Azure App Configuration diagnostic logs record that a key/value was created, updated, or deleted, but not the actual value that was written.

As mentioned in MSDOC, the audit logs include details such as the operation, key, caller, IP address, and timestamp, but not the key's value. Therefore, it's not possible to surface "when a key was set to a specific value" from diagnostic logs alone.

If you want to plot "times when key FeatureX became Enabled" or "when Mode changed to Maintenance", Azure App Configuration logs alone cannot provide that history because the value itself is never logged. You can follow any of the below alternatives:

Store configuration changes through a CI/CD pipeline that records the values (or hashes of values) in Git or another audit store.
Emit a custom log/event whenever your deployment updates App Configuration.
If you're using App Configuration revisions, query the revision history via the App Configuration API and export it periodically to Log Analytics or another data source that Grafana can query.

Hope this helps!
