Prometheus Go 🔗

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the prometheus-go monitor type to wrap the Prometheus Exporter to scrape Prometheus Go collector and Prometheus process collector metrics for Splunk Observability Cloud.

This integration is available on Linux and Windows.

Benefits 🔗

After you configure the integration, you can access these features:

Installation 🔗

Follow these steps to deploy this integration:

  1. Deploy the Splunk Distribution of the OpenTelemetry Collector to your host or container platform:

  2. Configure the integration, as described in the Configuration section.

  3. Restart the Splunk Distribution of the OpenTelemetry Collector.

Configuration 🔗

To use this integration of a Smart Agent monitor with the Collector:

  1. Include the Smart Agent receiver in your configuration file.

  2. Add the monitor type to the Collector configuration, both in the receiver and pipelines sections.

Example 🔗

To activate this integration, add the following to your Collector configuration:

receivers:
  smartagent/prometheus-go:
    type: prometheus-go
    host: localhost
    port: 2112
    ... # Additional config

Next, add the monitor to the service.pipelines.metrics.receivers section of your configuration file:

service:
  pipelines:
    metrics:
      receivers: [smartagent/prometheus-go]

Configuration settings 🔗

The following table shows the configuration options for the prometheus-go monitor:

skipVerify

no

bool
If both useHTTPS and skipVerify are true, the TLS

certificate of the exporter is not verified. Default value is false.

caCertPath

no

string
Path to the CA certificate that has signed the TLS certificate,

unnecessary if skipVerify is set to false.

clientCertPath

no

string
Path to the client TLS certificate to use for TLS required

connections.

without any filtering. This option has no effect when using the Prometheus exporter monitor directly, since there is no built-in filtering. Default value is false.

Metrics 🔗

The following metrics are available for this integration.

Notes 🔗

  • To learn more about the available in Splunk Observability Cloud see Metric types

  • In host-based subscription plans, default metrics are those metrics included in host-based subscriptions in Splunk Observability Cloud, such as host, container, or bundled metrics. Custom metrics are not provided by default and might be subject to charges. See Metric categories for more information.

  • In MTS-based subscription plans, all metrics are custom.

  • To add additional metrics, see how to configure extraMetrics in Add additional metrics

Non-default metrics (version 4.7.0+) 🔗

To emit metrics that are not default, you can add those metrics in the generic receiver-level extraMetrics config option. You don’t need to add to extraMetrics any metric derived from configuration options that don’t appear in the list of metrics.

To see a list of metrics that will be emitted you can run agent-status monitors after configuring the receiver in a running agent instance.
