The SDK's autoconfiguration module is used for basic configuration of the agent. Read the docs to find settings such as configuring export or sampling.
Here are some quick links into those docs for the configuration options for specific portions of the SDK & agent:
- Exporters
- Trace context propagation
- OpenTelemetry Resource and service name
- Batch span processor
- Sampler
- Span limits
- Using SPI to further configure the SDK
The agent can consume configuration from one or more of the following sources (ordered from highest to lowest priority):
- system properties
- environment variables
- the configuration file
- the
ConfigPropertySourceSPI
You can provide a path to agent configuration file by setting the corresponding property.
