Overview

Light Prometheus Receiver is a component that can scrape Prometheus metrics from a Prometheus exporter endpoint and convert them to OTLP metrics. It is intended to be used as a replacement for the Simple Prometheus Receiver as it is more efficient and has a smaller memory footprint.

The receiver is under active development which means that configuration interface can change.

Configuration

The following settings are required:

  • endpoint (no default): Address to request Prometheus metrics. This is the same endpoint that Prometheus scrapes to collect metrics. IMPORTANT: This receiver currently does require the metric path to be included in the endpoint. For example, if the endpoint is localhost:1234, the metrics path must be included, e.g. localhost:1234/metrics. This likely will be changed in the future.

The following settings can be optionally configured:

  • collection_interval (default = 30s): The internal at which metrics should be scraped by this receiver.
  • resource_attributes: Resource attributes to be added to all metrics emitted by this receiver. The following options are available to configure resource attributes:
    • service.name:
      • enabled: (default: true)
    • service.instance.id:
      • enabled: (default: true)
    • net.host.name:
      • enabled: (default: false)
    • net.host.port:
      • enabled: (default: false)
    • http.scheme:
      • enabled: (default: false)
  • HTTP Client Configuration options

The full list of configuration options exposed for this receiver are documented here with an example here.
