# Read metrics from one or many redis servers
[[inputs.redis]]
  ## specify servers via a url matching:
  ##  [protocol://][username:password]@address[:port]
  ##  e.g.
  ##    tcp://localhost:6379
  ##    tcp://username:password@192.168.99.100
  ##    unix:///var/run/redis.sock
  ##
  ## If no servers are specified, then localhost is used as the host.
  ## If no port is specified, 6379 is used
  servers = ["tcp://localhost:6379"]

  ## Optional. Specify redis commands to retrieve values
  # [[inputs.redis.commands]]
  #   # The command to run where each argument is a separate element
  #   command = ["get", "sample-key"]
  #   # The field to store the result in
  #   field = "sample-key-value"
  #   # The type of the result
  #   # Can be "string", "integer", or "float"
  #   type = "string"

  ## Specify username and password for ACL auth (Redis 6.0+). You can add this
  ## to the server URI above or specify it here. The values here take
  ## precedence.
  # username = ""
  # password = ""

  ## Optional TLS Config
  ## Check tls/config.go ClientConfig for more options
  # tls_enable = true
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = true
