You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: client.rb
    path of file: ./repos/redis_dashboard/lib/redis_dashboard
    
    the code of the file until where you have to start completion: class RedisDashboard::Client
  attr_reader :url, :connection

  def initialize(url)
    @url = url
    @connection ||= Redis.new(url: url)
  end

  def clients
    connection.client("list")
  end

  def config
    array_reply_to_hash(connection.config("get", "*"))
  end

  def info
    connection.info
  end

  def stats
    stats = connection.info("commandstats").sort { |a, b| b.last["usec"].to_i <=> a.last["usec"].to_i }
    total = stats.reduce(0) { |total, stat| total += stat.last["usec"].to_i }
    stats.each { |stat| stat.last["impact"] = stat.last["usec"].to_f * 100 / total }
    stats
  end

  def slow_commands
    connection.slowlog("get", config["slowlog-max-len"]).map do |entry|
      cmd = RedisDashboard::Command.new
      cmd.id = entry[0]
      cmd.timestamp = entry[1]
      cmd.microseconds = entry[2]
      cmd.command = entry[3]
      cmd
    end.sort{ |left, right| right.microseconds <=> left.microseconds }
