The following tables show which features are implemented by each OpenTelemetry language implementation.
+
means the feature is supported, -
means it is not supported, N/A
means
the feature is not applicable to the particular language, blank cell means the
status of the feature is not known.
For the Optional
column, X
means the feature is optional, blank means the
feature is required, and columns marked with *
mean that for each type of
exporter (OTLP and Zipkin), implementing at least one of the supported
formats is required. Implementing more than one format is optional.
