- Jaeger Environment
- `JAEGER_SERVICE_NAME`: The name of the service being instrumented (`JAEGER_SERVICE_NAME` = `OTEL_SERVICE_NAME`).
- `JAEGER_AGENT_HOST`: The host name or IP address of the Jaeger agent to use for sending trace data.
- `JAEGER_AGENT_PORT`: The port number of the Jaeger agent to use for sending trace data.
- `JAEGER_SAMPLER_TYPE`: The type of sampling to use for tracing (e.g. const, probabilistic, rateLimiting, remote).
- `JAEGER_SAMPLER_PARAM`: The parameter value to use for the selected sampler type.
- `JAEGER_SAMPLER_MANAGER_HOST_PORT`: The host name and port of the remote sampling manager to use (if using remote sampling).
- `JAEGER_REPORTER_LOG_SPANS`: Whether to log spans instead of sending them to a Jaeger agent (e.g. true or false).
- `JAEGER_REPORTER_MAX_QUEUE_SIZE`: The maximum number of spans that can be queued before they are sent to a Jaeger agent.
- `JAEGER_REPORTER_FLUSH_INTERVAL`: The interval at which to flush the span queue and send spans to a Jaeger agent (e.g. 1 * time.Second).
- `JAEGER_REPORTER_LOCAL_AGENT_HOST_PORT`: The host and port of the local Jaeger agent, if using UDP instead of HTTP.
- `JAEGER_REPORTER_COLLECTOR_ENDPOINT`: The endpoint URL of the Jaeger collector (e.g. `http://localhost:14268/api/traces`).
