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.

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

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

# 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
