Settings: OpenTelemetry

Enable OpenTelemetry support

Use this option to enable or disable the whole OpenTelemetry functionality.

Launch OpenTelemetry host on startup

The OTLP receiver starts automatically so that it is ready before you launch an application.

To start or stop the receiver, select the OpenTelemetry node in the OpenTelemetry tool window and use the toolbar buttons.

Activate the Services tool window for run configuration

When this checkbox is selected, launching a supported run configuration will activate the Services window instead of Run window or Debug window

Overwrite OpenTelemetry environment variables

While the receiver is running, the plugin supplies OTEL_EXPORTER_OTLP_ENDPOINT and the related OTLP environment variables when you run or debug an already instrumented application from a supported run configuration. These variables point the application's exporter to the built-in receiver.

While the receiver is running, the plugin also supplies these variables to every new integrated terminal session. An instrumented application launched from that terminal can therefore connect without additional endpoint configuration. A terminal session keeps the environment it received when it opened. Open a new session if you restart the receiver on a different port.

To keep the OTLP endpoint configured in your run configurations and terminal environment, clear this checkbox.

Use fixed OTLP server port

Use this checkbox to start the OpenTelemetry server on the specified port. You may need to use a fixed port to route the log streams from apps started locally outside the IDE.

Use fixed MCP server port
