    database: 0,
    pool_size: 10
  )
  config.ttl = 10.minutes
  config.prefix = "redis_stats"
end

# add method
t0 = Time.local

# ...
# some code
# ...

t1 = Time.local

# `key` - any string key
# `duration` - duration of executed code, milliseconds
RedisStats.add(key: "foo", duration: (t1 - t0).total_milliseconds)

# stats method
# Retrieves statistics from Redis.
RedisStats.stats
# => {
#   "foo" => {
#     "5m" => "0.3ms",   # last 5 minutes
#     "30m" => "0.5ms",  # last 30 minutes
#     "1d" => "0.55ms",  # last day
#     "max" => "0.7ms",  # max stored duration
#     "min" => "0.05ms", # min stored duration
#     "count" => "100"   # count of stored records
