Exec Output Plugin

This plugin sends telegraf metrics to an external application over stdin.

The command should be defined similar to docker's exec form:

["executable", "param1", "param2"]

On non-zero exit stderr will be logged at error level.

For better performance, consider execd, which runs continuously.

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"

  ## Data format to output.
  ## Each data format has its own unique set of configuration options, read
