Add tags to Azure functions - Application Insights

Adding the Tag in Your Function

To add the tag in your Azure function, you need to add a reference to System.Diagnostics and then call Activity.Current.AddTag to add your tag in the application insights log.

For example, a function that has a property "Account Number" could add this to the log thus:

#region Tracing telemetry
   Activity.Current.AddTag("Account Number", accountnumber);
#endregion

Querying the Tag

In your application insights query, you can use the customDimension function to access your custom tag.
