Network interface I/O 🔗

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the net-io monitor type to report I/O metrics about network interfaces.

Benefits 🔗

     receivers: [net-io]

Configuration settings 🔗

The following table shows the configuration options for the net-io integration:

Option	Required	Type	Description
`interfaces`	no	`list of strings`	The network interfaces to send metrics about. (default: `[* !/^lo\d$/ !/^docker./ !/^t(un\|ap)\d$/ !/^veth.$/ !/^Loopback*/]`)

On Linux hosts, this monitor relies on the /proc filesystem. If the underlying host’s /proc file system is mounted somewhere other than /proc, specify the path using the top-level configuration procPath.
