etcd server 🔗

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the etcd monitor type to report etcd server metrics under the /metrics path on its client port. Optionally, you can ediy location using --listen-metrics-urls. This integration only collects metrics from the Prometheus endpoint.

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 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/etcd:
    type: etcd
    ... # Additional config

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

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

Configuration settings 🔗

The following table shows the configuration options for this monitor:

Option	Required	Type	Description
`httpTimeout`	no	`int64`	HTTP timeout duration for both read and writes. This should be a duration string that is accepted by https://golang.org/pkg/time/#ParseDuration (default: `10s`)
`username`	no	`string`	Basic Auth username to use on each request, if any.
`password`	no	`string`	Basic Auth password to use on each request, if any.
`useHTTPS`	no	`bool`	If `true`, the agent will connect to the server using HTTPS instead of plain HTTP. (default: `false`)
`httpHeaders`	no	`map of strings`	A map of HTTP header names to values. Comma separated multiple values for the same message-header is supported.
`skipVerify`	no	`bool`	If useHTTPS is `true` and this option is also `true`, the exporter TLS cert will not be verified. (default: `false`)
`caCertPath`	no	`string`	Path to the CA cert that has signed the TLS cert, unnecessary if `skipVerify` is set to `false`.
`clientCertPath`	no	`string`	Path to the client TLS cert 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: `false`)
`metricPath`	no	`string`	Path to the metrics endpoint on the exporter server, usually `/metrics` (the default). (default: `/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, only when embedding it in other monitors. (default: `false`)

Metrics 🔗

The following metrics are available for this integration:

Notes 🔗

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 more about metric categories.
To add additional metrics, see how to configure extraMetrics using the Collector.
