# Ethtool Input Plugin This plugin collects ethernet device statistics. The available information strongly depends on the network device and driver. ⭐ Telegraf v1.13.0 🏷️ system, network 💻 linux ## 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][CONFIGURATION.md] for more details. [CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins ## Configuration ```toml @sample.conf # 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: ```text [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. ```sh 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. ## Example Output ```text ethtool,driver=igb,host=test01,interface=mgmt0
