What is the role of an exporter in OpenTelemetry?

The role of an exporter in OpenTelemetry is to send telemetry data to one or more backends. Exporters bridge the gap between the data collected by OpenTelemetry and its ultimate storage and analysis destinations, which could include various observability tools and cloud services.

When an application generates telemetry data, such as traces, metrics, or logs, this data does not inherently know where it should be sent or how it should be processed after collection. This is where exporters come in; they are responsible for taking that telemetry data and formatting it appropriately for consumption by the target backend systems, ensuring that the data is correctly transmitted and interpreted by the receiving service.

This capability is essential as it enables dynamic routing and management of data across different monitoring and observability platforms, providing flexibility and scalability for users as they can easily change their data destinations without altering the data collection process.

The other options pertain to different functionalities within the telemetry ecosystem but do not accurately describe the specific function of an exporter.
