Prometheus Exporter

Status
Stability beta
Supported pipeline types metrics
Distributions core, contrib

Exports data in the Prometheus format, which allows it to be scraped by a Prometheus server.

Getting Started

The following settings are required:

  • endpoint (no default): the address on which metrics will be exposed by the Prometheus scrape handler.

The following settings can be optionally configured:

  • const_labels (no default): key/values that are applied for every exported metric.
  • namespace (no default): if set, exports metrics under the provided value.
  • send_timestamps (default = false): if true, sends the timestamp of the underlying metric sample in the response.
  • metric_expiration (default = 5m): defines how long metrics are exposed without updates
  • resource_to_telemetry_conversion
    • enabled (default = false): If enabled is true, all the resource attributes will be converted to metric labels by default.

Example:

exporters:
  prometheus:
    endpoint: "1.2.3.4:1234"
    namespace: test-space
    const_labels:
      label1: value1
      "another label": spaced value
    send_timestamps: true
    metric_expiration: 180m
    resource_to_telemetry_conversion:
      enabled: true

Metric names and labels normalization

OpenTelemetry metric names and attributes are normalized to be compliant with Prometheus naming rules. Details on this normalization process are described in the Prometheus translator module.
