Overview

OpenTelemetry HAProxy metrics in an HAProxy dashboard

The HAProxy receiver allows for collection of HAProxy metrics and access to the HAProxy Overview dashboard. Configure the receiver according to the specifications of the latest version of the haproxyreceiver.

For more information, see the OpenTelemetry project documentation for the HAProxy receiver.

Setup

To collect HAProxy metrics with OpenTelemetry for use with Datadog:

  1. Configure the HAProxy receiver in your OpenTelemetry Collector configuration.
  2. Ensure the OpenTelemetry Collector is configured to export to Datadog.

See the HAProxy receiver documentation for detailed configuration options and requirements.
