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:

View metrics. You can create your own custom dashboards, and most monitors provide built-in dashboards as well. For information about dashboards, see View dashboards in Splunk Observability Cloud.
View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Use navigators in Splunk Infrastructure Monitoring.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Search the Metric Finder and Metadata catalog.

Installation 🔗

Follow these steps to deploy this integration:

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

Configuration 🔗

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

Include the Smart Agent receiver in your configuration file.
Add the monitor type to the Collector configuration, both in the receiver and pipelines sections.

See how to Use Smart Agent monitors with the Collector.
See how to set up the Smart Agent receiver.
For a list of common configuration options, refer to Common configuration settings for monitors.
Learn more about the Collector at Get started: Understand and use the Collector.

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:

Option	Required	Type	Description
`httpTimeout`	no	`int64`	HTTP timeout duration for both reads and writes. Must be a duration string accepted by https://golang.org/pkg/time/#ParseDuration. Default value is `10s`.
`username`	no	`string`	User name to use on each request.
`password`	no	`string`	Password to use on each request.
`useHTTPS`	no	`bool`	If true, the agent connects to the server using HTTPS instead of plain HTTP. Default value is `false`.
`httpHeaders`	no	`map of strings`	A map of HTTP header names to values. Comma-separated multiple values for the same message-header are supported.
`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.
`clientKeyPath`	no	`string`	Path to the client TLS key to use for TLS required connections.
`host`	yes	`string`	Host of the exporter.
`port`	yes	`integer`	Port of the exporter.
`useServiceAccount`	no	`bool`	Use pod service account to authenticate. Default value is `false`.
`metricPath`	no	`string`	Path to the metrics endpoint on the exporter server. The default value is `/metrics`.
`sendAllMetrics`	no	`bool`	Send all the metrics that come out of the Prometheus exporter 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 Observability Cloud see Metric types
In host-based subscription plans, default metrics are those metrics included in host-based subscriptions in 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.
