# ethflux

*ethflux* is an InfluxDB data gatherer for ethtool-style network interface information. It uses the Linux SIOCETHTOOL ioctl interface to obtain network interface statistics and other runtime data and outputs them in InfluxDB's [line protocol format]([https://docs.influxdata.com/influxdb/v1.4/write_protocols/line_protocol_reference/) for further propagation.

## Getting the code

```
go get github.com/DCSO/ethflux.git
```

## Building

```
go build -v
```

will produce an `ethflux` binary.

## Usage

```
Usage: ethflux [-help] [-quiet] [-measurement=string] <iface pattern>
  -help
    	show help
  -measurement string
    	name of measurement to use in line (default "ethtool")
  -quiet
    	do not show warnings
```
The interface parameter supports regular expressions, e.g. `wl.*` would match `wlp4s0` etc.

## Example

```
$ ./ethflux enp175s0f1

In Telegraf, for instance, one could use this software using the `exec` input:
```toml
[[inputs.exec]]
  commands = ["ethflux enp175s0f1"]
  timeout = "5s"
  data_format = "influx"
```

## Built Using

* [fluxline](https://github.com/DCSO/fluxline) - Encoder for InfluxDB LineProtocol
* [ethtool](https://github.com/safchain/ethtool) - Go library to talk to the kernel
