Gem for ruby ​​on rails traffic metric?

Question

Ruby on Rails

Gentlemen, Ruby. Please tell me a gem to track site visitors. We need to count the number of unique visitors, and it is desirable to have built-in helpers for a nice graphic display (plotting a graph)

Answer 1

There is no normal gem. If you do this with records in the database, it will slow down. I would do it on Redis.
We put Redis, we connect gems.

gem 'redis'
gem 'redis-rails'

We make ourselves config/initializers/redis.rb. We write there:
Then in application_controller.rb we write:

before_action :tracking_users
def tracking_users
  $redisTrackUsers.set(request.remote_ip, true, ex: 24*60*60) // через день поле уничтожится
end

users who have logged in in the last 24 hours:
And then whenever, for example, you can drop it into the database.
