Interface traffic 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the Interface traffic monitor via the Smart Agent Receiver.

The Interface plugin collects 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 all interfaces but want to exclude some, or only collect information of some selected interfaces, you can select the “interesting” interfaces using the plugin’s configuration.

Note: This monitor is deprecated in favor of the net-io monitor. You should switch to that monitor as this monitor will be removed in a future release of the agent. Note that 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.

Installation 🔗

This monitor is provided by the Smart Agent and is available by using the SignalFx Smart Agent Receiver in the Splunk Distribution of OpenTelemetry Collector.

To install this integration:

  1. Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform.

  2. Configure the monitor, as described in the next section.

Configuration 🔗

The Splunk Distribution of OpenTelemetry Collector allows embedding a Smart Agent monitor configuration in an associated Smart Agent Receiver instance.

Note: Providing an Interface traffic monitor entry in your Smart Agent or Collector configuration is required for its use. Use the appropriate form for your agent type.

Smart Agent 🔗

To activate this monitor in the Smart Agent, add the following to your agent configuration:

monitors:  # All monitor config goes under this key
 - type: collectd/interface
   ...  # Additional config

See Smart Agent example configuration for an autogenerated example of a YAML configuration file, with default values where applicable.

Splunk Distribution of OpenTelemetry Collector 🔗

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.

See configuration examples for specific use cases that show how the Splunk 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*$/ /^docker.*/ /^t(un|ap)\d*$/ /^veth.*$/])
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:
