# System network metricset
The System `network` metricset provides network IO metrics collected from the operating system. One event is created for each network interface.
This metricset is available on:
- FreeBSD
- Linux
- macOS
- Windows


## Configuration

<definitions>
  <definition term="interfaces">
    By default metrics are reported from all network interfaces. To select which interfaces metrics are reported from, use the `interfaces` configuration option. The value must be an array of interface names. For example:
  </definition>
</definitions>

```yaml
metricbeat.modules:
- module: system
  metricsets: [network]
  interfaces: [eth0]
```

This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.

## Fields

For a description of each field in the metricset, see the [exported fields](https://www.elastic.co/docs/reference/beats/metricbeat/exported-fields-system) section.
