Naive question but worth asking: did you make sure to update ApplicationInsights.config with your application's instrumentation key? Its not necessary that you do that. Live Metrics Stream also has a custom channel that powers the live streaming of telemetry. No other counter is supported in Linux. I had similar issue. We provide two implementations in the Microsoft.ApplicationInsights SDK: ApplicationInsightsApplicationIdProvider and DictionaryApplicationIdProvider. This static provider relies on your configured instrumentation key/application ID pairs. For information on tracking EventSource events, see Using EventSource events. This channel offers minimal reliability guarantees because it doesn't retry sending telemetry after a failure. Why is there a voltage on my HDMI and coaxial cables? They're sent whenever the application starts again. This section assumes that you're using a web app based on the standard MVC web app template for the ASP.NET Framework. My mistake, I didn't realize IHttpContextAccessor creates an object reference so the constructor doesn't need to be hit multiple times. Add or confirm your Application Insights connection string. The default configuration collects ILogger Warning logs and more severe logs. Dependency collection is enabled by default. So, if your server is a cluster of several machines, the actual volume of telemetry will be multiplied accordingly. On March 31, 2025, support for instrumentation key ingestion will end. If you require configuration beyond setting the connection string, you're required to remove auto-injection as described and manually add the JavaScript SDK. you may getting page views telemetry since the js code has its own configuration for the ikey, and it is not using the ApplicationInsights.config file. For Windows systems, the SDK automatically creates a temporary local folder in the %TEMP% or %LOCALAPPDATA% directory and restricts access to administrators and the current user only. Application Insights can collect the following telemetry from your ASP.NET Core application: Requests Dependencies Exceptions Performance counters Heartbeats Logs We'll use an MVC application example.
