Interface traffic 🔗

Description 🔗

Note: This monitor is deprecated in favor of the net-io monitor. Switch to that monitor as the Smart Agent is deprecated. The net-io monitor uses the interface dimension to identify the network card instead of the plugin_instance dimension, but otherwise the metrics are the same. To learn more, see Network interface I/O.

The Splunk Distribution of OpenTelemetry Collector provides this integration as the interface monitor by using the SignalFx Smart Agent Receiver.

Use this integration to collect information about the traffic (octets per second), packets per second and errors of interfaces (of course number of errors during one second).

If you’re not interested in collecting information from all interfaces, select the interfaces you want to monitor using the plugin’s configuration.

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 🔗

This monitor type is available in the Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector. You can use existing Smart Agent monitors as OpenTelemetry Collector metric receivers with the Smart Agent Receiver.

This monitor type requires a properly configured environment on your system in which you’ve installed a functional Smart Agent release bundle. The Collector provides this bundle in the installation paths for x86_64/amd64.

To activate this monitor type in the Collector, add the following lines to your configuration (YAML) file:

Configuration example 🔗

To activate this monitor in the Splunk Distribution of OpenTelemetry Collector, add the following to your agent configuration:

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

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

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

See configuration examples for specific use cases that show how the Splunk Distribution of OpenTelemetry Collector can integrate and complement existing environments.

Configuration settings 🔗

The following table shows the configuration options for this monitor:

Option	Required	Type	Description
`excludedInterfaces`	no	`list of strings`	List of interface names to exclude from monitoring (default: `[/^lo\d$/ /^docker./ /^t(un
`includedInterfaces`	no	`list of strings`	List of all the interfaces you want to monitor, all others will be ignored. If you set both `included` and `excludedInterfaces`, only `includedInterfaces` will be honored.

Metrics 🔗

The following metrics are available for this integration:
