Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See CONFIGURATION.md for more details.

Configuration

# Read metrics from one or many mcrouter servers.
[[inputs.mcrouter]]
  ## An array of address to gather stats about. Specify an ip or hostname
  ## with port. ie tcp://localhost:11211, tcp://10.0.0.1:11211, etc.
  servers = ["tcp://localhost:11211", "unix:///var/run/mcrouter.sock"]

  ## Timeout for metric collections from all servers.  Minimum timeout is "1s".
  # timeout = "5s"
