Open Telemetry Protocol (OTLP) 1.0.0 released

OpenTelemetry Protocol (OTLP) 1.0.0 was recently released.OTLP specificationsDescribes the mechanisms for encryption, transmission, and distribution of telemetry data between telemetry resources, intermediate nodes such as aggregators, and telemetry backends. It is a general-purpose telemetry data distribution protocol designed within the scope of the OpenTelemetry project.

The framework provides a set of APIs, libraries, agents, and aggregation services to capture distributed traces and metrics. Additionally, the specification reached version 1.0.0 status in early 2021, as reported by InfoQ.

Open telemetry isAPI To easily leverage application code to generate telemetry data and seamlessly route the metrics collection across different SDK applications. . OTel allows developers to leverage code and capture telemetry data.Language-specific integrationAnd libraries. These include, for example, software development kits (OTel SDKs) for Java, Golang, .NET and Python. Telemetry data is collected from these libraries andOpen the telemetry collector OTLP is used to exchange data between client and server. OTLP defines a sequence diagram that strictly adheres to the traceability, metrics, and log data model.

OpenTelemetry Collector acts as a central repository, receiving, processing and exporting telemetry data collected from various sources, as well as a local proxy for single applications and a gateway for multiple applications.

The OTLP is responsible for how data is serialized, deserialized, and transferred between network services. This protocol strictly adheres to the data model, describes a sequential diagram, andOther telemetry protocolsIt aims to solve the problem.

Responsible for honeycomb developmentMartin ThwaitesHe told InfoQ:

OTLP is the core of OpenTelemetry and is more powerful than ever. Moving to version 1 means taking this to the next level. Most vendors have already adapted to accepting data using the OTLP protocol. Version 1 gives some much-needed credibility to OLTP, and hopefully adding this support will help overcome the few remaining hurdles.

Moreover, he said:

Most importantly, there will be more interoperability and less need to add proprietary protocol libraries to their stacks. This is a huge benefit for people who want more visibility into what’s happening in their apps.

Finally, the OpenTelemetry project is currently part of the CNCFNursery projectthat it.
