Currently, IExtension field on ITelemetry is not delivered to Azure Monitor backend and data is not available for querying/charting in UI experiences.
Serializing IExtension into the custom dimensions and measurements will allow successful delivery / storage and display in Azure Monitor.
For instance, an event with an extension like this:
public class MyExtension : IExtension
{
public int field;
public string anotherField;
public IExtension DeepClone()
{
var other = new MyExtension();
other.field = this.field;
other.anotherField = this.anotherField;
return other;
}
public void Serialize(ISerializationWriter serializationWriter)
{
serializationWriter.WriteProperty("Field", this.field);
serializationWriter.WriteProperty("AnotherField", this.anotherField);
}
}
…
...
RequestTelemetry requestTelemetry = new RequestTelemetry();
requestTelemetry.Extension = new MyExtension() { field = 42, anotherField = "value" };
client.TrackRequest(requestTelemetry);
