Ingest Prometheus metrics using an OpenTelemtry Collector on Kubernetes

If you’re already generating Prometheus metrics for your system, you can send those metrics directly to Lightstep Observability using the OpenTelemetry Collector, running in Kubernetes.

The OpenTelemetry Collector ingests Prometheus metrics from targets, such as Envoy, RabbitMQ, HAProxy, and other infrastructure components. These components use the Prometheus exporter to send metrics to the Collector. The Collector then uses the Prometheus receiver to scrape the target metrics, and the Lightstep OTLP exporter to send the metrics to Lightstep.

To send Prometheus metrics to Lightstep, you need to do the following:

• Deploy the Collector to Kubernetes
  • You can deploy the collector either as a single instance or as a daemon set. Read this topic to help determine which deployment scenario is best for your environment.
• Begin ingesting Prometheus metrics. Lightstep offers a number of pre-built integrations for many services that emit Prometheus metrics.
• Performance test your set up.
