+# Executable Output Plugin
+
+This plugin writes metrics to an external application via `stdin`. The command
+will be executed on each write creating a new process. Metrics are passed in
+one of the supported [data formats][data_formats].
+
+The executable and the individual parameters must be defined as a list.
+All outputs of the executable to `stderr` will be logged in the Telegraf log.
+
+> [!TIP]
+> For better performance consider execd which runs continuously.

+## Global configuration options <!-- @/docs/includes/plugin_config.md -->
+
+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
+
+```toml @sample.conf
+# Send metrics to command as input over stdin
+[[outputs.exec]]
+  ## Command to ingest metrics via stdin.
+  command = ["tee", "-a", "/dev/null"]
+
+  ## Environment variables
+  ## Array of "key=value" pairs to pass as environment variables
+  ## e.g. "KEY=value", "USERNAME=John Doe",
+  ## "LD_LIBRARY_PATH=/opt/custom/lib64:/usr/local/libs"
+  # environment = []
+
+  ## Timeout for command to complete.
+  # timeout = "5s"
+
+  ## Whether the command gets executed once per metric, or once per metric batch
+  ## The serializer will also run in batch mode when this is true.
+  # use_batch_format = true
+
+  ## Data format to output.
+  ## Each data format has its own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  # data_format = "influx"
