Stack Overflow | The World's Largest Online Community for Developers In a suitable initialization class, for example, AppStart in Global.asax.cs, insert your processor into the chain: Telemetry clients created after this point will use your processors. It also allows you to modify the endpoints that your resource will use as a destination for your telemetry. A singleton instance of TelemetryClient is already registered in the DependencyInjection container, which shares TelemetryConfiguration with the rest of the telemetry. It might take a few minutes for telemetry to appear in the portal and analytics, but Live Metrics shows CPU usage of the running process in near real time. In this case, you're responsible for ensuring that the directory is secured. A similar approach can be used for sending custom metrics to Application Insights by using the GetMetric API.

Read more about data protection and privacy. For others, services.AddSingleton(new MyCustomTelemetryInitializer() { fieldName = "myfieldName" }); is required. The Flush() method that's implemented by this channel isn't synchronous. To set the key for all instances of TelemetryClient, including standard telemetry modules, do this step in an initialization method, such as global.aspx.cs in an ASP.NET service: If you want to send a specific set of events to a different resource, you can set the key for a specific telemetry client: To get a new key, create a new resource in the Application Insights portal. You can add as many processors as you like. This channel is independent of the regular telemetry channel, and this document doesn't apply to it. Configure a snapshot collection for ASP.NET applications. You can choose to drop it from the stream or give it to the next processor in the chain.

AzureRoleEnvironmentTelemetryInitializer updates the RoleName and RoleInstance properties of the Device context for all telemetry items with information extracted from the Azure runtime environment. Each telemetry module collects a specific type of data and uses the core API to send the data. But I want to create some custom events and log those as well, but I cannot get any oft he Custom Events to show up in the Azure portal. For example, you can filter out telemetry about requests from robots or successful dependency calls. See Troubleshoot missing application telemetry in Azure Monitor Application Insights. For non-Windows systems, the SDK will automatically create a local storage folder based on the following logic: The SDK stores telemetry items in local storage during network problems or during throttling. When the in-memory capacity has been exceeded, Transmission instances are stored on local disk up to a limit of 50 MB. More info about Internet Explorer and Microsoft Edge.
