The OpenTelemetry Collector, when configured with a Prometheus receiver, provides an integration with Couchbase to ingest metrics. The Collector fetches metrics from the configured path in the Couchbase configuration file and sends it to the Prometheus exporter. From there the metrics are received and processed by the Prometheus receiver and exported to Lightstep Observability.

To complete the integration, you will:

  • Configure the Collector to use the Couchbase endpoint as a scrape target for the Prometheus receiver.
  • Enable the integration by adding it to a pipeline

Prerequisites

You’ve configured the Collector to export metric data to Lightstep Observability.

Configure the Collector receiver

In the Collector configuration file, configure the Prometheus receiver to use the Couchbase endpoint as a scrape target.

The OpenTelemetry repo’s readme provides additional details about Prometheus receiver configuration.

Enable the Collector receiver

Once the Couchbase 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 metrics are reporting to Lightstep on the Metrics details page in Project settings.

  1. In Lightstep, click Project settings > Metric details.

  2. Search for Couchbase metric names. Search for metric

    See the Couchbase documentation 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.
