rails-monitoring

Rails engine that provides a JSON API which serves Sidekiq and Whenever status information from a HTTP-auth protected endpoint. This status information is gathered by scheduling a frequently running job that saves timestamps in Redis.

Installation

Add gem to your project:

gem 'rails-monitoring'

Mount engine in routes.rb:

Rails.application.routes.draw do
  mount Rails::Monitoring::Engine => '/monitoring'
end

Schedule job in whenever's schedule.rb:

every 5.minutes do
  runner 'Rails::Monitoring::Status.refresh'
end

Be sure that your parent app provides HTTP basic authentication credentials using an initializer

# app/config/initializers/monitoring.rb
Rails::Monitoring.http_auth_name = 'user'
Rails::Monitoring.http_auth_password = 'password'

This engine's controller inherits from ApplicationController by default. You can change this using the parent_controller option

Rails::Monitoring.parent_controller = 'SomeOtherController'

Usage

Navigate to /monitoring/status and receive Sidekiq status information:

{
  "timestamps": {
    "whenever_ran": "2018-01-23 15:05:02",
    "sidekiq_performed": "2018-01-23 15:05:02",
    "requested": "2018-01-23 15:08:28"
  },
  "sidekiq": {
    "active_workers": 0,
    "queue_sizes": {
      "mailers": 0,
      "default": 0,
      "scheduled": 0,
