Ethtool Input Plugin

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

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Returns ethtool statistics for given interfaces
# This plugin ONLY supports Linux
[[inputs.ethtool]]
  ## List of interfaces to pull metrics for
  # interface_include = ["eth0"]

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

  ## Plugin behavior for downed interfaces
  ## Available choices:
  ##   - expose: collect & report metrics for down interfaces
  ##   - skip: ignore interfaces that are marked down
  # down_interfaces = "expose"

  ## Reading statistics from interfaces in additional namespaces is also
  ## supported, so long as the namespaces are named (have a symlink in
  ## /var/run/netns). The telegraf process will also need the CAP_SYS_ADMIN
  ## permission.
  ## By default, only the current namespace will be used. For additional
  ## namespace support, at least one of `namespace_include` and
  ## `namespace_exclude` must be provided.
  ## To include all namespaces, set `namespace_include` to `["*"]`.
  ## The initial namespace (if anonymous) can be specified with the empty
  ## string ("").

  ## List of namespaces to pull metrics for
  # namespace_include = []

  ## List of namespace to ignore when pulling metrics.
  # namespace_exclude = []

  ## 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.

Namespaces

Metrics from interfaces in additional namespaces will be retrieved if either namespace_include or namespace_exclude is configured (to a non-empty list). This requires CAP_SYS_ADMIN permissions to switch namespaces, which can be granted to telegraf in several ways. The two recommended ways are listed below:

Using systemd capabilities

If you are using systemd to run Telegraf, you may run systemctl edit telegraf.service and add the following:

[Service]
AmbientCapabilities=CAP_SYS_ADMIN
Configuring executable capabilities

If you are not using systemd to run Telegraf, you can configure the Telegraf executable to have CAP_SYS_ADMIN when run.

sudo setcap CAP_SYS_ADMIN+epi $(which telegraf)

N.B.: This capability is a filesystem attribute on the binary itself. The attribute needs to be re-applied if the Telegraf binary is rotated (e.g. on installation of new a Telegraf version from the system package manager).

Metrics

Metrics are dependent on the network device and driver.
