Sidekiq::Status

Gem Version Code Climate Build Status Dependency Status Inline docs

An extension to Sidekiq message processing to track your jobs. Inspired by resque-status and mostly copying its features, using Sidekiq's middleware.

Fully compatible with ActiveJob.

Supports the latest versions of Sidekiq and all the way back to 3.x.

Installation

Add this line to your application's Gemfile:

gem 'sidekiq-status'

And then execute:

$ bundle

Or install it yourself as:

gem install sidekiq-status

Setup Checklist

To get started:

Configuration

To use, add sidekiq-status to the middleware chains. See Middleware usage on the Sidekiq wiki for more info.

require 'sidekiq'
require 'sidekiq-status'

Sidekiq.configure_client do |config|
  config.client_middleware do |chain|
    # accepts :expiration (optional)
    chain.add Sidekiq::Status::ClientMiddleware, expiration: 30.minutes # default
  end
end

Sidekiq.configure_server do |config|
  config.server_middleware do |chain|
    # accepts :expiration (optional)
    chain.add Sidekiq::Status::ServerMiddleware, expiration: 30.minutes # default
  end
  config.client_middleware do |chain|
    # accepts :expiration (optional)
    chain.add Sidekiq::Status::ClientMiddleware, expiration: 30.minutes # default
  end
end

After that you can use your jobs as usual. You may also include the Sidekiq::Status::Worker module in your jobs if you want the additional functionality of tracking progress and storing / retrieving job data.

class MyJob
  include Sidekiq::Worker

  def perform(*args)
  # your code goes here
  end
end

To overwrite expiration on a per-worker basis, write an expiration method like the one below:

class MyJob
  include Sidekiq::Worker

  def expiration
    @expiration ||= 60 * 60 * 24 * 30 # 30 days
  end

  def perform(*args)
    # your code goes here
  end
end

The job status and any additional stored details will remain in Redis until the expiration time is reached. It is recommended that you find an expiration time that works best for your workload.

Expiration Times

As sidekiq-status stores information about jobs in Redis, it is necessary to set an expiration time for the data that gets stored. A default expiration time may be configured at the time the middleware is loaded via the :expiration parameter.

As explained above, the default expiration may also be overridden on a per-job basis by defining it within the job itself via a method called #expiration.

The expiration time set will be used as the Redis expire time, which is also known as the TTL (time to live). Once the expiration time has passed, all information about the job's status and any custom data stored via sidekiq-status will disappear.

It is advised that you set the expiration time greater than the amount of time required to complete the job.

The default expiration time is 30 minutes.

Retrieving Status

You may query for job status any time up to expiration:

job_id = MyJob.perform_async(*args)
# :queued, :working, :complete, :failed or :interrupted, nil after expiry (30 minutes)
status = Sidekiq::Status::status(job_id)
Sidekiq::Status::queued?      job_id
Sidekiq::Status::working?     job_id
Sidekiq::Status::complete?    job_id
Sidekiq::Status::failed?      job_id
Sidekiq::Status::interrupted? job_id

Important: If you try any of the above status method after the expiration time, the result will be nil or false.

ActiveJob Support

Version 0.7.0 has added full support for ActiveJob. The status of ActiveJob jobs will be tracked automatically.

To also enable job progress tracking and data storage features, simply add the Sidekiq::Status::Worker module to your base class, like below:

# app/jobs/application_job.rb
class ApplicationJob < ActiveJob::Base
  include Sidekiq::Status::Worker
end

# app/jobs/my_job.rb
class MyJob < ApplicationJob
  def perform(*args)
    # your code goes here
  end
end

Tracking Progress and Storing Data

sidekiq-status comes with a feature that allows you to track the progress of a job, as well as store and retrieve any custom data related to a job. To use, just include the Sidekiq::Status::Worker module in your jobs.

class MyJob
  include Sidekiq::Worker
  include Sidekiq::Status::Worker # Important!

  def perform(*args)
    # your code goes here

    # the common idiom to track progress of your task
    total 100 # by default
    at 5, "Almost done" # 5/100 = 5 % completion

    # a way to associate data with your job
    store vino: 'veritas'

    # a way of retrieving stored data
    # remember that retrieved data is always String|nil
    vino = retrieve :vino
  end
end

job_id = MyJob.perform_async(*args)
data = Sidekiq::Status::get_all job_id
data # => {status: 'complete', update_time: 1360006573, vino: 'veritas'}
Sidekiq::Status::get     job_id, :vino #=> 'veritas'
Sidekiq::Status::at      job_id #=> 5
Sidekiq::Status::total   job_id #=> 100
Sidekiq::Status::message job_id #=> "Almost done"
Sidekiq::Status::pct_complete job_id #=> 5

Unscheduling

scheduled_job_id = MyJob.perform_in 3600
Sidekiq::Status.cancel scheduled_job_id #=> true
# doesn't cancel running jobs, this is more like unscheduling, therefore an alias:
Sidekiq::Status.unschedule scheduled_job_id #=> true

# returns false if invalid or wrong scheduled_job_id is provided
Sidekiq::Status.unschedule some_other_unschedule_job_id #=> false
Sidekiq::Status.unschedule nil #=> false
Sidekiq::Status.unschedule '' #=> false
# Note: cancel and unschedule are alias methods.

Important: If you schedule a job and then try any of the status methods after the expiration time, the result will be either nil or false. The job itself will still be in Sidekiq's scheduled queue and will execute normally. Once the job is started at its scheduled time, sidekiq-status' job metadata will once again be added back to Redis and you will be able to get status info for the job until the expiration time.

Deleting Job Status by Job ID

Job status and metadata will automatically be removed from Redis once the expiration time is reached. But if you would like to remove job information from Redis prior to the TTL expiration, Sidekiq::Status#delete will do just that. Note that this will also remove any metadata that was stored with the job.

# returns number of keys/jobs that were removed
Sidekiq::Status.delete(job_id) #=> 1
Sidekiq::Status.delete(bad_job_id) #=> 0

Sidekiq Web Integration

This gem provides an extension to Sidekiq's web interface with an index at /statuses.

Sidekiq Status Web

As of 0.7.0, status information for an individual job may be found at /statuses/:job_id.

Sidekiq Status Web

Adding the Web Interface

To use, setup the Sidekiq Web interface according to Sidekiq documentation and add the Sidekiq::Status::Web require:

require 'sidekiq/web'
require 'sidekiq-status/web'

Testing

Drawing analogy from sidekiq testing by inlining, sidekiq-status allows to bypass redis and return a stubbed :complete status. Since inlining your sidekiq worker will run it in-process, any exception it throws will make your test fail. It will also run synchronously, so by the time you get to query the job status, the job will have been completed successfully. In other words, you'll get the :complete status only if the job didn't fail.

Inlining example:

You can run Sidekiq workers inline in your tests by requiring the sidekiq/testing/inline file in your {test,spec}_helper.rb:

require 'sidekiq/testing/inline'

To use sidekiq-status inlining, require it too in your {test,spec}_helper.rb:

require 'sidekiq-status/testing/inline'
