Rmetrics

Rmetrics is a gem that relies on ActiveSupport to get all metrics in your Rails application, such as: ActionController, ActiveView, ActiveRecord, ActionMailer, ActiveSupport, ActiveJob, ActionCable and ActiveStorage

Add this line to your application's Gemfile:

gem 'rmetrics'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rmetrics

To start get all the metrics you want, you have to call Rmetrics.setup inside a file in config/initializers/rmetrics.rb. One example of how you should setup rmetrics is below:

Rmetrics.setup do |config|
  config.action_controller = ['start_processing.action_controller',
                              'process_action.action_controller',
                              'redirect_to.action_controller']
  config.active_view = ['render_template.action_view',
                        'render_partial.action_view']
  config.active_record = ['instantiation.active_record',
                          'sql.active_record']
  config.action_mailer = ['receive.action_mailer']
  config.active_support = ['cache_read.active_support']
  config.active_job = ['enqueue_at.active_job']
  config.action_cable = ['perform_action.action_cable']
  config.active_storage = ['service_upload.active_storage']
  config.db_config = { username: ENV['INFLUX_USERNAME'],
                       password: ENV['INFLUX_PASSWORD'],
                       database: ENV['INFLUX_DATABASE'],
                       host: ENV['INFLUX_HOST'],
                       port: ENV['INFLUX_PORT'], retry: 10 }
end

After that, you have to subscribe to all Action or Active you want, one example is given below:

events = Rmetrics::Events.new
events.controller_subscribe_events
events.record_subscribe_events
events.view_subscribe_events

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
