Notable tracks notable requests and background jobs and stores them in your database. What makes a request or job notable? There are a number of default situations, but ultimately you decide what interests you.

By default, Notable tracks:

• errors
• 404s
• slow requests and jobs
• timeouts
• validation failures
• CSRF failures
• unpermitted parameters
• blocked and throttled requests

You can track custom notes as well.

🍊 Battle-tested at Instacart

Add this line to your application’s Gemfile:

gem "notable"

And run:

rails generate notable:requests
rails generate notable:jobs
rails db:migrate

To explore the data, check out Blazer.

A Notable::Request is created for:

• errors
• 404s
• slow requests
• timeouts from Slowpoke
• validation failures
• CSRF failures
• unpermitted parameters
• blocked and throttled requests from Rack Attack

A Notable::Job is created for:

• errors
• slow jobs
• validation failures

Create a custom note inside a request or job with:

Notable.track("Note Type", "Optional extra info")

Disable tracking in certain environments

Notable.enabled = Rails.env.production?

Set slow threshold

Notable.slow_request_threshold = 5.seconds

Custom user method

Notable.user_method = lambda do |env|
  env["warden"].try(:user) || env["action_controller.instance"].try(:current_visit)
end

Custom track method

Notable.track_request_method = lambda do |data, env|
  Notable::Request.create!(data)
end

Skip tracking CSRF failures

skip_before_action :track_unverified_request

Anonymize IP addresses

Notable.mask_ips = true

Set slow threshold

Notable.slow_job_threshold = 60.seconds

To set a threshold for a specific job, use:

class CustomJob < ApplicationJob
  def notable_slow_job_threshold
    5.minutes
  end
end

Custom track method
