Consul datastore 🔗

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the Consul datastore monitor type to monitor Consul datastores and collect metrics from the following endpoints:

This integration is only available on Kubernetes and Linux.

This integration works with Consul 0.7.0 and higher.

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 OpenTelemetry Collector to your host or container platform:
- Install on Kubernetes
- Install on Linux
Configure the monitor, as described in the Configuration section.
Restart the Splunk Distribution of 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.

Read more on how to Use Smart Agent monitors with the Collector.
See how to set up the Smart Agent receiver.
Learn about config options in Collector default configuration.

Example 🔗

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

receivers:
  smartagent/consul:
    type: collectd/consul
    ...  # Additional config

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

service:
  pipelines:
    metrics:
      receivers: [smartagent/consul]

Configuration options 🔗

If you are running a version of Consul earlier than 0.9.1, configure each Consul agent you want to monitor to send metrics to the OpenTelemetry Collector. To do so, add the following configuration to each Consul agent configuration file:

{"telemetry":
   {"statsd_address": "<agent host>:<agent port, default 8125>"}
}

Configuration settings 🔗

The following table shows the configuration options for this integration:

Option	Required	Type	Description
`pythonBinary`	no	`string`	Path to a python binary that should be used to execute the Python code. If not set, a built-in runtime will be used. Can include arguments to the binary as well.
`host`	yes	`string`
`port`	yes	`integer`
`aclToken`	no	`string`	Consul ACL token
`useHTTPS`	no	`bool`	Set to `true` to connect to Consul using HTTPS. You can figure the certificate for the server with the `caCertificate` config option. (default: `false`)
`telemetryServer`	no	`bool`	(default: `false`)
`telemetryHost`	no	`string`	IP address or DNS to which Consul is configured to send telemetry UDP packets. Relevant only if `telemetryServer` is set to `true`. (default: `0.0.0.0`)
`telemetryPort`	no	`integer`	Port to which Consul is configured to send telemetry UDP packets. Relevant only if `telemetryServer` is set to `true`. (default: `8125`)
`enhancedMetrics`	no	`bool`	Set to `true` to activate the collection all metrics from Consul runtime telemetry send using UDP or from the `/agent/metrics` endpoint. (default: `false`)
`caCertificate`	no	`string`	If Consul server has HTTPS activated for the API, specifies the path to the CA Certificate.
`clientCertificate`	no	`string`	If client-side authentication is activated, specifies the path to the certificate file.
`clientKey`	no	`string`	If client-side authentication is activated, specifies the path to the key file.
`signalFxAccessToken`	no	`string`

These 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.
