CNCF Project vs CNCF Member Project 这有什么区别？

OpenTelemetry 在遇到以下无法解决的问题情况下出现了。

于是需要设计一个可观测的系统来解决以上问题，在设计上需要满足基本的需求^[4]：

不同类型的遥测，我们称之为信号，主要的信号是追踪

OpenTelemetry 是一个跨领域的关注点(cross-cutting concern)

但是，来自谷歌：the particular instruments used in a piece of music / measuring instruments regarded collectively.

OpenTelemetry protocol (OTLP)，定义了 Open Telemetry 里 Tracing\Metrics\Logging 的 protobuf 的协议格式。比如 Tracing

Propagators: Used to serialize and deserialize specific parts of telemetry data such as span context and Baggage in Spans.

Traces can extend beyond a single process. This requires context propagation, a mechanism where identifiers for a trace are sent to remote processes.

otel.SetTextMapPropagator(propagation.TraceContext{})

TextMapPropagator injects values into and extracts values from carries as text.

A carrier is the medium used by Propagators to read values from and write values to.

OpenTelemetry and Newrelic 结合 , 中间通过 opentelemetry-go 来连接。

也可以通过 opentelemetry-collector (e.g. binary, sidecar, or daemonset). 方式来做。

What is Tracing Analysis，从 Architecture 看是支持 Opentracing Basing SDK

Tracing Analysis is compatible with SDKs from various open source communities and supports the OpenTracing standard.
