🛑 Breaking changes 🛑

• rpc: Rename rpc.client|server.duration to rpc.client|server.call.duration, change RPC duration metrics from milliseconds to seconds, and clarify metric and span duration semantics for streaming. (#​383, #​2961)

• rpc: Rename

• rpc.grpc.request.metadata and rpc.connect_rpc.request.metadata to rpc.request.metadata

• rpc.grpc.response.metadata and rpc.connect_rpc.response.metadata to rpc.response.metadata
  (#​2869, #​3169)

• rpc: Merge rpc.method and rpc.service into fully-qualified rpc.method attribute. Clarify how to handle possible high cardinality of rpc.method in edge cases. Clarify rpc.method usage in span names. (#​2863, #​3196, #​3223)

• rpc: Deprecate rpc.grpc.status_code, rpc.connect_rpc.error_code and rpc.jsonrpc.error_code attributes in favor of the more general rpc.response.status_code attribute.
  (#​1504, #​2920)

• rpc: Align RPC conventions with naming guidelines. Renames:

• rpc.system to rpc.system.name. The values are also updated to match
  naming guidelines: connect_rpc is renamed to connectrpc;
  apache_dubbo is renamed to dubbo;
  java_rmi, dotnet_wcf, and onc_rpc are not included in the new enum.

• rpc.jsonrpc.request_id to jsonrpc.request.id.

• rpc.jsonrpc.version to jsonrpc.protocol.version.

• system, linux: Rename *.linux.memory metrics and attributes to *.memory.linux (#​1661)

🚩 Deprecations 🚩

• peer: The peer.service attribute has been deprecated in favor of service.peer.name. (#​2945)
  The peer.service attribute has been renamed to service.peer.name to align with the service.{name|namespace} resource attributes.
• process: Introduce process.unix.file_descriptor.count and process.windows.handle.count metrics.
  Deprecate process.open_file_descriptor.count
  (#​3188)

💡 Enhancements 💡

• cloud: Add gcp.agent_engine as a value for cloud.platform (#​2957)

• cloud: Add Oracle Cloud Infrastructure to SemConv Areas list (#​3190)

• cloud: Add Hetzner Cloud to cloud.provider and cloud.platform (#​2758)

• cloud: Add Linode (Akamai Cloud) to cloud.provider and linode_cloud_compute to cloud.platform (#​2756)

• cloud: Add Vultr Cloud to cloud.provider and cloud.platform (#​2757)

• k8s: Add missing entity associations to k8s and container metrics (#​3213)

• k8s: Adds k8s.pod.ip, k8s.pod.hostname and k8s.pod.start_time attributes (#​3171)

• k8s: Define missing roles for entity attributes (#​3135)

• k8s: Promote a selection of k8s and container attributes to alpha (#​3120)
  The selected attributes being promoted are used by the Collector Contrib components
  that are targeting stability. See opentelemetry-collector-contrib/#​44130

• k8s: Define roles for k8s entities' attributes (#​3017)

• mcp: Add MCP semantic conventions (#​2043, #​2083)

• otel: Add otel.event.name attribute for use by non-OTLP exporters and logging libraries. (#​2913)
  The otel.event.name attribute can be used by:

  • Non-OTLP exporters to emit the EventName
  • Applications using existing logging libraries to add event name information that can be used to set the EventName field by Collector or SDK components

• pprof: add various pprof attributes to support lossless conversion from and to OTel profiles. (#​3078)

• rpc: Use consistent set of attributes between RPC spans and metrics (#​2922, #​3197)

  • Use rpc.response.status_code on common metrics and spans.
  • Make error.type note consistent between metrics and spans.
  • Promote notes on rpc.method and rpc.service to attribute definition.

• rpc: Mark rpc.system.name, rpc.method, rpc.service, server.address, and server.port as sampling relevant attributes in RPC spans.
  (#​3202)

• service: Splits service into three entities: namespace, service and instance. (#​2880)

• service: service.peer.name and service.peer.namespace have been introduced as the replacement for peer.service to describe remote services that use both a name and a namespace. (#​2945)
  The peer.service attribute could not fully represent the service.{name|namespace} resource attributes;
  service.peer.name and service.peer.namespace provide a more complete representation.

🧰 Bug fixes 🧰

• rpc: Demote server.address from required to conditionally required (when available) on RPC spans and metrics. Update server.port requirement level accordingly. (#​3236)
