OpenTelemetry.Exporter.OTLP

The OTLP Exporter is the recommend exporter format to use where possible.

A number of vendors offer support for exporting traces, logs, and metrics using the vendor-agnostic OTLP protocol.

Additionally, the OTLP format is supported by the OpenTelemetry Collector.

The OpenTelemetry Collector offers a vendor-agnostic implementation of how to receive, process and export telemetry data. It removes the need to run, operate, and maintain multiple agents/collectors. This works with improved scalability and supports open-source observability data formats (e.g. Jaeger, Prometheus, Fluent Bit, etc.) sending to one or more open-source or commercial back-ends. The local Collector agent is the default location to which instrumentation libraries export their telemetry data.
