The `netstat` collector reads data from `/proc/net/dev` and outputs a handful **node** metrics. If a metric is not required, it can be excluded from forwarding it to the sink.

* `read_sectors`
* `read_ms`
* `writes`
* `writes_merged`

Metrics per device (with `device` tag):

* `disk_free` (unit `GBytes`)
Global metrics:
