• (Contrib) hostmetricsreceiver: Add new Windows-exclusive process.handles metric. (#21379)

• (Contrib) resourcedetectionprocessor: Adds a way to configure the list of added resource attributes by the processor (#21482)
  Users can now configure what resource attributes are gathered by specific detectors.
  Example configuration:

  resourcedetection:
    detectors: [system, ec2]
    system:
      resource_attributes:
        host.name:
          enabled: true
        host.id:
          enabled: false
    ec2:
      resource_attributes:
        host.name:
          enabled: false
        host.id:
          enabled: true
  

  For example, this config makes host.name being set by system detector, and host.id by ec2 detector.
  Moreover:

  • Existing behavior remains unaffected as all attributes are currently enabled by default.
  • The default attributes 'enabled' values are defined in metadata.yaml.
  • Future releases will introduce changes to resource_attributes enabled values.
  • Users can tailor resource detection process to their needs and environment.

• (Contrib) k8sclusterreceiver: Add explicitly k8s.node.allocatable_pods to the list of Kubernetes node metrics available, which went missing during the pdata translation (#23839)
