OTel Me More: OpenTelemetry Project News – Vol 28

OpenTelemetry Project News

The OpenTelemetry log data model is now official, aiming to successfully represent 3 sorts of logs and events: system formats, third-party applications, and first-party applications.

The OpenTelemetry Metrics API has been updated, specifying and explaining six metric instruments:

Name	Synchronous	Additive	Monotonic
Counter	Yes	Yes	Yes
UpDownCounter	Yes	Yes	No
ValueRecorder	Yes	No	No
SumObserver	No	Yes	Yes
UpDownSumObserver	No	Yes	No
ValueObserver	No	No	No

There is a new Collector exporter for Elastic. The exporter works by translating spans and metrics into the ND-JSON format expected by Elastic APM Server, and sending over HTTP.

There is now a Maintainer’s Meeting every Monday at 9 am PT, which can be found on the public calendar, with async conversations happening in the Gitter room.

These OpenTelemetry SIGs are looking for extra support! Open source efforts rely on developers like you -- get involved with one of these implementations:

• OTel-Rust is looking for contributors and maintainers
• OTel-PHP is looking for contributors and maintainers
• OTel-C++ is looking for contributors and maintainers
• OTel-Ruby has seen a lot of contributions, but would benefit from having more dedicated maintainers

This week’s Featured Issues:

• OpenTelemetry-C++ #79: Implement CorrelationContext
• OpenTelemetry-C++ #89: Implement a stdout exporter
