Mcrouter Input Plugin

This plugin gathers statistics data from a Mcrouter server.

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

# 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"
