Whenever we find the need to log custom telemetry for our App Service, we need to start working with the Application Insights SDK; the codeless solution isn . Instead, you get custom key-value pairs and can simply query for a given key having a given value. Plug-ins for the Application Insights SDK can customize how telemetry is enriched and processed before it's sent to the Application Insights service. Or, if you use fiddler, can you see outbound requests to "dc.servies.visualstudio.com" going out from your app? You can create a storage directory yourself and configure the channel to use it.
