Prometheus Go 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the prometheus-go monitor type for the Smart Agent Receiver.

This monitor wraps the Prometheus Exporter to scrape Prometheus Go collector and Prometheus process collector metrics for Splunk Observability Cloud.

This monitor 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 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 Splunk Infrastructure Monitoring navigators.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Use the Metric Finder.

Installation 🔗

Follow these steps to deploy this integration:

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

Configuration 🔗

To use this Smart Agent monitor with the Collector, include the smartagent receiver and service pipeline in your configuration file. The Smart Agent receiver is fully supported only on x86_64/amd64 platforms.

Read more in Use Smart Agent monitors with the Collector.
Learn about config options in Collector default configuration.

See the examples below for more details.

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

To complete the receiver activation, you must also include the receiver in a metrics pipeline. To do this, add the receiver to the service > pipelines > metrics > receivers section of your configuration file. For example:

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.

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.
