Telegraf Plugin: Redis

Configuration:

# Read Redis's basic status information
[[inputs.redis]]
  ## specify servers via a url matching:
  ##  [protocol://][:password]@address[:port]
  ##  e.g.
  ##    tcp://localhost:6379
  ##    tcp://:[email protected]
  ##
  ## If no servers are specified, then localhost is used as the host.
  ## If no port is specified, 6379 is used
  servers = ["tcp://localhost:6379"]

Example Output:

Using this configuration:

[[inputs.redis]]
  ## specify servers via a url matching:
  ##  [protocol://][:password]@address[:port]
  ##  e.g.
  ##    tcp://localhost:6379
  ##    tcp://:[email protected]
  ##
  ## If no servers are specified, then localhost is used as the host.
  ## If no port is specified, 6379 is used
  servers = ["tcp://localhost:6379"]

When run with:

./telegraf -config telegraf.conf -input-filter redis -test

It produces:
