Once you’ve integrated with AWS CloudWatch, you have access to all metrics for Amazon Neptune, a fully managed graph database service.

See all available AWS integrations.

To verify metrics are reporting, search for the metrics in the Metric details page in Project settings.

The following table shows the Neptune metrics ingested by Lightstep.
