The System diskio metricset provides disk IO metrics collected from the operating system. One event is created for each disk mounted on the system.

This metricset is available on:

• Linux
• macOS (requires 10.10+)
• Windows
• FreeBSD (amd64)

Configuration [_configuration_6]

diskio.include_devices : When the diskio metricset is enabled, you can use the diskio.include_devices option to define a list of device names to pre-filter the devices that are reported. Filters only exact matches. If not set or given [] empty array, all disk devices are returned

The following example config returns metrics for devices matching include_devices:

```yaml
metricbeat.modules:
- module: system
  metricsets: ["diskio"]
  diskio.include_devices: ["sda", "sda1"]
```
