The Elastic Infra Metrics Processor can be used to bridge the gap between OTEL and Elastic Infra Metrics. It is used to power the Curated UI's in Elastic. This processor uses the elastic/opentelemtery-lib library, which derives and adds Elastic compatible metrics from the OTEL metrics without altering the OTEL metrics. The processor should be used only with the below receivers and exporter.

Receivers: It should be used with the Host Metrics Receiver and Kubelet Stats Receiver.
Exporter: It should be used only with the Elasticsearch Exporter.

Configuration

processors:
  elasticinframetrics:
    # Defines if System Infra Metrics compatibility should be enabled
    # default = true
    add_system_metrics: {true,false}
    # Defines if K8s Infra Metrics compatibility should be enabled
    # default = true
    add_k8s_metrics: {true,false}
    # Defines if all Metrics -both initial and remapped- are going to be kept. 
    # If enabled, then only the remapped metrics are ingested. 
    # default = false
    drop_original : {true,false}
