Processing Telemetry Data

URL: http://localhost:{PORT}, where localhost indicates the local host IP address 127.0.0.1.

After event subscription with telemetry APIs, the extension receives telemetry data from FunctionGraph using the telemetry listener. Each POST request contains an Event object array in the body.

There are three event types you can subscribe to: platform, function, and extension.
