The `netstat` collector reads data from `/proc/net/dev` and outputs a handful **node** metrics. If a device is not required, it can be excluded from forwarding it to the sink. Commonly the `lo` device should be excluded.
The `netstat` collector reads data from `/proc/net/dev` and outputs a handful **node** metrics. With the `include_devices` list you can specify which network devices should be measured. **Note**: Most other collectors use an _exclude_ list instead of an include list.
Metrics:
* `bytes_in`
* `bytes_out`
* `pkts_in`
* `pkts_out`
* `net_bytes_in` (`unit=bytes/sec`)
* `net_bytes_out` (`unit=bytes/sec`)
* `net_pkts_in` (`unit=packets/sec`)
* `net_pkts_out` (`unit=packets/sec`)
The device name is added as tag `device`.
