Recently, the OpenTelemetry Protocol (OTLP) 1.0.0 was released. OTLP specification describes telemetry data’s encoding, transport, and delivery mechanism between telemetry sources, intermediate nodes such as collectors, and telemetry backends. It is a general-purpose telemetry data delivery protocol designed in the scope of the OpenTelemetry project.
OpenTelemetry (OTEL) is an open-source Cloud Native Computing Foundation (CNCF) project formed from the merger of the OpenCensus and OpenTracing projects. It is a vendor-neutral open-source Observability framework for instrumenting, generating, collecting, and exporting telemetry data such as traces, metrics, and logs. The framework provides a set of APIs, libraries, agents, and collector services for capturing distributed traces and metrics. In addition, its specification reached 1.0.0 version status earlier in 2021 and was reported by InfoQ.
