Module resource

Representations of entities producing telemetry.

A Resource is an immutable representation of the entity producing telemetry as attributes. For example, a process producing telemetry that is running in a container on Kubernetes has a Pod name, it is in a namespace and possibly is part of a Deployment which also has a name. All three of these attributes can be included in the Resource. Note that there are certain “standard attributes” that have prescribed meanings.

Resource detectors

ResourceDetectors are used to detect resource from runtime or environmental variables. The following are provided by default with this SDK.

• EnvResourceDetector - detect resource from environmental variables.
• TelemetryResourceDetector - detect telemetry SDK’s information.

The OS and Process resource detectors are packaged separately in the opentelemetry-resource-detector crate.

Structs

• EnvResourceDetector
  EnvResourceDetector extract resource from environment variable OTEL_RESOURCE_ATTRIBUTES. See OpenTelemetry Resource Spec for details.
• Iter
  An iterator over the entries of a Resource.
• Resource
  An immutable representation of the entity producing telemetry as attributes. Utilizes Arc for efficient sharing and cloning.
• SdkProvidedResourceDetector
  There are attributes which MUST be provided by the SDK as specified in the Resource SDK specification. This detector detects those attributes and if the attribute cannot be detected, it uses the default value.
• TelemetryResourceDetector
  Detect the telemetry SDK information used to capture data recorded by the instrumentation libraries.

Traits

• ResourceDetector
