The OpenTelemetry Collector provides an integration with the Collector’s host to ingest metrics. When configured to use the Host metrics integration, the Collector fetches CPU metrics from the configured path in the Host metrics receiver. From there the metrics are processed and exported to Lightstep Observability.

To complete the integration, you will:

  • Configure and enable the Host metrics receiver for the Collector


  • You’ve installed the Collector onto the host machine
  • You’ve configured the Collector to export metric data to Lightstep Observability.

Configure the Collector receiver

In the Collector configuration file, add Host metrics as a receiver and set the following (values are not needed):


The OpenTelemetry repo readme provides additional details about Host metrics configuration.

Enable the Collector receiver

Once the Host metrics receiver is configured, enable it by adding it to one or more pipelines as described in the Collector configuration documentation.

Validate metrics are reporting to Lightstep

You can validate that the metrics are reporting to Lightstep from the Metric details section of the Project Settings page.

  1. Open the Project settings page.

  2. In the Metric details section, search for Host metrics metric names. Search for metric

    See the receiver’s metadata file for a complete list of emitted metrics.

  3. If needed, click on the metric to edit the description and how the units are displayed in Lightstep.

Create a dashboard for the metrics

Use the Lightstep Terraform Provider to create a dashboard for the metrics. Host metrics dashboard in Lightstep
