# Ethtool Input Plugin

The ethtool input plugin pulls ethernet device stats. Fields pulled will depend on the network device and driver.

### Configuration:

```toml
# Returns ethtool statistics for given interfaces
[[inputs.ethtool]]
  ## List of interfaces to pull metrics for
  # interface_include = ["eth0"]

  ## List of interfaces to ignore when pulling metrics.
  # interface_exclude = ["eth1"]

  ## Some drivers declare statistics with extra whitespace, different spacing,
  ## and mix cases. This list, when enabled, can be used to clean the keys.
  ## Here are the current possible normalizations:
  ##  * snakecase: converts fooBarBaz to foo_bar_baz
  ##  * trim: removes leading and trailing whitespace
  ##  * lower: changes all capitalized letters to lowercase
  ##  * underscore: replaces spaces with underscores
  # normalize_keys = ["snakecase", "trim", "lower", "underscore"]
```

Interfaces can be included or ignored using:

- `interface_include`
- `interface_exclude`

Note that loopback interfaces will be automatically ignored.

### Metrics:

Metrics are dependent on the network device and driver.

### Example Output:
