Telemetry Attributes

This document defines attributes for telemetry SDK.

Attribute	Type	Description	Examples	Stability
telemetry.distro.name	string	The name of the auto instrumentation agent or distribution, if used. [1]	parts-unlimited-java
telemetry.distro.version	string	The version string of the auto instrumentation agent or distribution, if used.	1.2.3
telemetry.sdk.language	string	The language of the telemetry SDK.	cpp; dotnet; erlang
telemetry.sdk.name	string	The name of the telemetry SDK as defined above. [2]	opentelemetry
telemetry.sdk.version	string	The version string of the telemetry SDK.	1.2.3

[1]: Official auto instrumentation agents and distributions SHOULD set the telemetry.distro.name attribute to a string starting with opentelemetry-, e.g. opentelemetry-java-instrumentation.

[2]: The OpenTelemetry SDK MUST set the telemetry.sdk.name attribute to opentelemetry. If another SDK, like a fork or a vendor-provided implementation, is used, this SDK MUST set the telemetry.sdk.name attribute to the fully-qualified class or module name of this SDK’s main entry point or another suitable identifier depending on the language. The identifier opentelemetry is reserved and MUST NOT be used in this case. All custom identifiers SHOULD be stable across different versions of an implementation.

telemetry.sdk.language has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.

Value	Description	Stability
cpp	cpp
dotnet	dotnet
erlang	erlang
go	go
java	java
nodejs	nodejs
php	php
python	python
ruby	ruby
rust	rust
swift	swift
webjs	webjs
