OpenTelemetry
OpenTelemetry is an open-source project that provides standard APIs, SDKs and tools for generating and collecting telemetry such as traces, metrics and logs.
OpenTelemetry, often shortened to OTel, is a Cloud Native Computing Foundation (CNCF) project launched in 2019 through the merger of the OpenTracing and OpenCensus projects. It offers instrumentation libraries for many programming languages and a Collector that receives, processes and exports telemetry data.
Because it collects telemetry in a vendor-neutral format, teams use it to combine a collection layer with storage and analysis tools from different providers.
