influxdb-rails

This library is now updated to require influxdb-ruby v0.2.0 and greater, meaning that only InfluxDB v0.9.x and higher will be supported. If you want to use this library with InfluxDB v0.8.x, you'll need to use v0.1.10 or earlier. You will also need to manually specify gem 'influxdb', '0.1.9' in your gemfile.

We encourage you to submit a pull request if you have a contribution. Maintained by @toddboom and @dmke.

Automatically instrument your Ruby on Rails applications and write the metrics directly into InfluxDB.

Install

$ [sudo] gem install influxdb-rails

Or add it to your Gemfile, etc.

Usage

To get things set up, just create an initializer:

$ cd /to/you/rails/application
$ touch config/initializers/influxdb-rails.rb

In this file, you can configure the InfluxDB::Rails adapter. The default config should look something like this:

InfluxDB::Rails.configure do |config|
  config.influxdb_database = "rails"
  config.influxdb_username = "root"
  config.influxdb_password = "root"
  config.influxdb_hosts    = ["localhost"]
  config.influxdb_port     = 8086

  # config.retry = false
  # config.async = false
  # config.open_timeout = 5
  # config.read_timeout = 30
  # config.max_delay = 300
  # config.time_precision = 'ms'

  # config.series_name_for_controller_runtimes = "rails.controller"
  # config.series_name_for_view_runtimes       = "rails.view"
  # config.series_name_for_db_runtimes         = "rails.db"
end

Out of the box, you'll automatically get reporting of your controller, view, and db runtimes for each request. You can also call through to the underlying InfluxDB::Client object to write arbitrary data like this:

InfluxDB::Rails.client.write_point "events",
  tags:   { url: "/foo", user_id: current_user.id },
  values: { value: 0 }

Additional documentation for InfluxDB::Client lives in the influxdb-ruby repo.
