Resource attributes

[preview] This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

A resource attribute is a key/value pair containing information about the entity producing telemetry. Resource attributes are mapped to Elastic Common Schema (ECS) fields like service.*, cloud.*, process.*, etc. These fields describe the service and the environment that the service runs in.

The examples shown here set the Elastic (ECS) service.environment field for the resource, i.e. service, that is producing trace events. Note that Elastic maps the OpenTelemetry deployment.environment field to the ECS service.environment field on ingestion.

OpenTelemetry agent

Use the OTEL_RESOURCE_ATTRIBUTES environment variable to pass resource attributes at process invocation.

export OTEL_RESOURCE_ATTRIBUTES=deployment.environment=production

OpenTelemetry collector

Use the resource processor to set or apply changes to resource attributes.
