The HAProxy receiver generates metrics by polling periodically the HAProxy process through a dedicated socket or HTTP URL. The supported pipeline type is metrics. See Process your data with pipelines for more information.

Note: Out-of-the-box dashboards and navigators aren’t supported for the HAProxy receiver yet, but are planned for a future release.

Get started

Follow these steps to configure and activate the component:

Deploy the Splunk Distribution of the OpenTelemetry Collector to your host or container platform:
Configure the receiver as described in the next section.
Restart the Collector.

Sample configurations

To activate the HAProxy receiver, add haproxy to the receivers section of your configuration file, as shown in the following example:

receivers:
  haproxy:
    endpoint: file:///var/run/haproxy.ipc
    collection_interval: 1m
    metrics:

To complete the configuration, include the receiver in the metrics pipeline of the service section of your configuration file. For example:

service:
  pipelines:
    metrics:
      receivers: [haproxy]

Configuration options

You can configure the following settings:

endpoint. Required. Path to the endpoint exposed by HAProxy for communications. It can be a local file socket or a HTTP URL.
collection_interval. Optional, 1m by default. The scraping collection interval.

Activate or deactivate specific metrics

You can activate or deactivate specific metrics by setting the enabled field in the metrics section for each metric. For example:

receivers:
  samplereceiver:
    metrics:
      metric-one:
        enabled: true
      metric-two:
        enabled: false

The following is an example of host metrics receiver configuration with activated metrics:

receivers:
  hostmetrics:
    scrapers:
      process:
        metrics:
          process.cpu.utilization:
            enabled: true

Note: Deactivated metrics aren’t sent to Splunk Observability Cloud.

Billing

If you’re in a MTS-based subscription, all metrics count towards metrics usage.
If you’re in a host-based plan, metrics listed as active (Active: Yes) on this document are considered default and are included free of charge.
