Status: Alpha Overview Environment variables provide a mechanism to propagate context and baggage information across process boundaries when network protocols are not applicable. This specification extends the API Propagators to define how the TextMapPropagator can be used with environment variables. Common systems where context propagation via environment variables is useful include: Batch processing systems CI/CD environments Command-line tools Propagator Mechanisms Propagating context via ...| OpenTelemetry
Status: Stable Overview Cross-cutting concerns send their state to the next process using Propagators, which are defined as objects used to read and write context data to and from messages exchanged by the applications. Each concern creates a set of Propagators for every supported Propagator type. Propagators leverage the Context to inject and extract data for each cross-cutting concern, such as traces and Baggage. Propagation is usually implemented via a cooperation of library-specific reque...| OpenTelemetry
Status: Stable, except where otherwise specified Tracer Provider Tracer Creation It SHOULD only be possible to create Tracer instances through a TracerProvider (see API). The TracerProvider MUST implement the Get a Tracer API. The input provided by the user MUST be used to create an InstrumentationScope instance which is stored on the created Tracer. Status: Development - The TracerProvider MUST compute the relevant TracerConfig using the configured TracerConfigurator, and create a Tracer who...| OpenTelemetry
We are excited to announce a new version of Centrifugo. It's an evolutionary step which makes Centrifugo cleaner and more intuitive to use.| centrifugal.dev
