Resource Detection Processor

Supported pipeline types: metrics, traces, logs

The resource detection processor can be used to detect resource information from the host, in a format that conforms to the OpenTelemetry resource semantic conventions, and append or override the resource value in telemetry data with this information.

Currently supported detectors include:

• Environment Variable: Reads resource information from the OTEL_RESOURCE_ATTRIBUTES environment variable. This is expected to be in the format <key1>=<value1>,<key2>=<value2>,..., the details of which are currently pending confirmation in the OpenTelemetry specification.

• System metadata: Queries the host machine to retrieve the following resource attributes:

  • host.name
  • os.type

• GCE Metadata: Uses the Google Cloud Client Libraries for Go to read resource information from the GCE metadata server to retrieve the following resource attributes:

  • cloud.provider ("gcp")
  • cloud.infrastructure_service ("gcp_compute_engine")
  • cloud.account.id
  • cloud.region
  • cloud.zone
  • host.id
  • host.image.id
  • host.type

• AWS EC2: Uses AWS SDK for Go to read resource information from the EC2 instance metadata API to retrieve the following resource attributes:

  • cloud.provider ("aws")
  • cloud.infrastructure_service ("aws_ec2")
  • cloud.account.id
  • cloud.region
  • cloud.zone
  • host.id
  • host.image.id
  • host.name
  • host.type

It also can optionally gather tags for the EC2 instance that the collector is running on. Note that in order to fetch EC2 tags, the IAM role assigned to the EC2 instance must have a policy that includes the ec2:DescribeTags permission.

EC2 custom configuration example:

detectors: ["ec2"]
ec2:
    # A list of regex's to match tag keys to add as resource attributes can be specified
    tags:
        - ^tag1$
        - ^tag2$
        - ^label.*$

• Amazon ECS: Queries the Task Metadata Endpoint (TMDE) to record information about the current ECS Task. Only TMDE V4 and V3 are supported.

  • cloud.provider ("aws")
  • cloud.infrastructure_service ("aws_ecs")
  • cloud.account.id
  • cloud.region
  • cloud.zone
  • aws.ecs.cluster.arn
  • aws.ecs.task.arn
  • aws.ecs.task.family
  • aws.ecs.launchtype (V4 only)
  • aws.log.group.names (V4 only)
  • aws.log.group.arns (V4 only)
  • aws.log.stream.names (V4 only)
  • aws.log.stream.arns (V4 only)

• Amazon Elastic Beanstalk: Reads the AWS X-Ray configuration file available on all Beanstalk instances with X-Ray Enabled.

  • cloud.provider ("aws")
  • cloud.infrastructure_service ("aws_elastic_beanstalk")
  • deployment.environment
  • service.instance.id
  • service.version

• Azure: Queries the Azure Instance Metadata Service to retrieve the following resource attributes:

  • cloud.provider ("azure")
  • cloud.infrastructure_service ("azure_vm")
  • cloud.region
  • cloud.account.id (subscription ID)
  • host.id (virtual machine ID)
  • host.name
  • azure.vm.size (virtual machine size)
  • azure.resourcegroup.name (resource group name)

Configuration

# a list of resource detectors to run, valid options are: "env", "system", "gce", "ec2", "ecs", "elastic_beanstalk", "azure"
detectors: [ <string> ]
# determines if existing resource attributes should be overridden or preserved, defaults to true
override: <bool>

The full list of settings exposed for this extension are documented here with detailed sample configurations here.

Functions

func NewFactory

func NewFactory() component.ProcessorFactory

NewFactory creates a new factory for ResourceDetection processor.

Types

type Config

type Config struct {
	configmodels.ProcessorSettings `mapstructure:",squash"`
	// Detectors is an ordered list of named detectors that should be
	// run to attempt to detect resource information.
	Detectors []string `mapstructure:"detectors"`
	// Timeout specifies the maximum amount of time that we will wait
	// before assuming a detector has failed. Defaults to 5s.
	Timeout time.Duration `mapstructure:"timeout"`
	// Override indicates whether any existing resource attributes
	// should be overridden or preserved. Defaults to true.
	Override bool `mapstructure:"override"`
	// DetectorConfig is a list of settings specific to all detectors
	DetectorConfig DetectorConfig `mapstructure:",squash"`
}

Config defines configuration for Resource processor.

type DetectorConfig

type DetectorConfig struct {
	// EC2Config contains user-specified configurations for the EC2 detector
	EC2Config ec2.Config `mapstructure:"ec2"`
}

DetectorConfig contains user-specified configurations unique to all individual detectors

func (*DetectorConfig) GetConfigFromType

func (d *DetectorConfig) GetConfigFromType(detectorType internal.DetectorType) internal.DetectorConfig
