The OpenTelemetry .NET Automatic Instrumentation supports a wide variety of libraries.
Instrumentations
All instrumentations are enabled by default for all signal types (traces, metrics, and logs).
You can disable all instrumentations for a specific signal type by setting the
OTEL_DOTNET_AUTO_{SIGNAL}_INSTRUMENTATION_ENABLED environment variable to
false.
For a more granular approach, you can disable specific instrumentations for a
given signal type by setting the
OTEL_DOTNET_AUTO_{SIGNAL}_{0}_INSTRUMENTATION_ENABLED environment variable to
false, where {SIGNAL} is the type of signal, for example TRACES, and {0}
is the case-sensitive name of the instrumentation.

OTEL_DOTNET_AUTO_TRACES_{0}_INSTRUMENTATION_ENABLED | Configuration pattern for enabling a specific trace instrumentation, where {0} is the uppercase ID of the instrumentation you want to enable. Overrides OTEL_DOTNET_AUTO_TRACES_INSTRUMENTATION_ENABLED. | Inherited from the current value of OTEL_DOTNET_AUTO_TRACES_INSTRUMENTATION_ENABLED | Experimental |
OTEL_DOTNET_AUTO_METRICS_INSTRUMENTATION_ENABLED | Disables all metric instrumentations. Overrides OTEL_DOTNET_AUTO_INSTRUMENTATION_ENABLED. | Inherited from the current value of OTEL_DOTNET_AUTO_INSTRUMENTATION_ENABLED | Experimental |
OTEL_DOTNET_AUTO_METRICS_{0}_INSTRUMENTATION_ENABLED | Configuration pattern for enabling a specific metric instrumentation, where {0} is the uppercase ID of the instrumentation you want to enable. Overrides OTEL_DOTNET_AUTO_METRICS_INSTRUMENTATION_ENABLED. | Inherited from the current value of OTEL_DOTNET_AUTO_METRICS_INSTRUMENTATION_ENABLED | Experimental |
OTEL_DOTNET_AUTO_LOGS_INSTRUMENTATION_ENABLED | Disables all log instrumentations. Overrides OTEL_DOTNET_AUTO_INSTRUMENTATION_ENABLED. | Inherited from the current value of OTEL_DOTNET_AUTO_INSTRUMENTATION_ENABLED | Experimental |
OTEL_DOTNET_AUTO_LOGS_{0}_INSTRUMENTATION_ENABLED | Configuration pattern for enabling a specific log instrumentation, where {0} is the uppercase ID of the instrumentation you want to enable. Overrides OTEL_DOTNET_AUTO_LOGS_INSTRUMENTATION_ENABLED. | Inherited from the current value of OTEL_DOTNET_AUTO_LOGS_INSTRUMENTATION_ENABLED | Experimental |
Traces instrumentations
Status: Mixed. Traces are stable, but particular instrumentation libraries are in Experimental status due to lack of stable semantic convention.
