resque-status is an extension to the resque queue system that provides simple trackable jobs.


resque-status provides a set of simple classes that extend resque’s default functionality (with 0% monkey patching) to give apps a way to track specific job instances and their status. It achieves this by giving job instances UUID’s and allowing the job instances to report their status from within their iterations.


resque-status *requires Redis >= 1.1* (though I recommend getting the latest stable version). You can download Redis here: or install it using homebrew (brew install redis).

Install the resque-status gem (which will pull in the dependencies).

gem install resque-status

With newer Rails add this to your Gemfile:

# Gemfile
gem 'resque-status'

Then in an initializer:

# config/initializers/resque.rb
Resque.redis = "your/redis/socket" # default localhost:6379
Resque::Plugins::Status::Hash.expire_in = (24 * 60 * 60) # 24hrs in seconds


The most direct way to use resque-status is to create your jobs using the Resque::Plugins::Status module. An example job would look something like:

class SleepJob
  include Resque::Plugins::Status

  def perform
    total = (options['length'] || 1000).to_i
    total.times do |i|
      num = i+1
      at(num, total, "At #{num} of #{total}")

One major difference is that instead of implementing perform as a class method, we do our job implementation within instances of the job class.

In order to queue a SleepJob up, we also won’t use Resque.enqueue, instead we’ll use the create class method which will wrap enqueue and creating a unique id (UUID) for us to track the job with.

job_id = SleepJob.create(length: 100)

This will create a UUID enqueue the job and pass the :length option on the SleepJob instance as options (as you can see above).

Now that we have a UUID its really easy to get the status:

status = Resque::Plugins::Status::Hash.get(job_id)

This returns a Resque::Plugins::Status::Hash object, which is a Hash (with benefits).

status.pct_complete #=> 0
status.status #=> 'queued'
status.queued? #=> true
status.working? #=> false
status.time #=> Time object
status.message #=> "Created at ..."

Once the worker reserves the job, the instance of SleepJob updates the status at each iteration using at()

status = Resque::Plugins::Status::Hash.get(job_id)
status.working? #=> true
status.num #=> 5 #=> 100
status.pct_complete #=> 5

If an error occurs within the job instance, the status is set to ‘failed’ and then the error is re-raised so that Resque can capture it.

Its also possible to get a list of current/recent job statuses:

Resque::Plugins::Status::Hash.statuses #=> [#<Resque::Plugins::Status::Hash>, ...]

Passing back data from the job

You may want to save data from inside the job to access it from outside the job.

A common use-case is web-triggered jobs that create files, later available for download by the user.

A Status is actually just a hash, so inside a job you can do:

set_status(filename: "myfilename")

Also, all the status setting methods take any number of hash arguments. So you could do:

completed('filename' => '/myfilename')

Kill! Kill! Kill!

Because we’re tracking UUIDs per instance, and we’re checking in/updating the status on each iteration (using at or tick) we can kill specific jobs by UUID.


The next time the job at job_id calls at or tick, it will raise a Killed error and set the status to killed.

Percent Complete and setting the message

Use at or tick to show progress in your job’s perform function (which is displayed on the resque-web status tab). This will also be where Killed is raised if the job is killed.

at(steps_completed, total_steps, "${steps_completed} of #{total_steps} steps completed!")


Since Redis is RAM based, we probably don’t want to keep these statuses around forever (at least until @antirez releases the VM feature). By setting expire_in, all statuses and their related keys will expire in expire_in seconds from the last time theyre updated:

Resque::Plugins::Status::Hash.expire_in = (60 * 60) # 1 hour


Recent versions of Resque introduced ‘Resque.inline` which changes the behavior to instead of enqueueing and performing jobs to just executing them inline. In Resque itself this removes the dependency on a Redis, however, `Resque::Status` uses Redis to store information about jobs, so though `inline` “works”, you will still need to use or mock a redis connection. You should be able to use a library like alongside `inline` if you really want to avoid Redis connections in your test.


Though the main purpose of these trackable jobs is to allow you to surface the status of user created jobs through your apps’ own UI, I’ve added a simple example UI as a plugin to resque-web.

To use, you need to setup a resque-web config file:

# ~/resque_conf.rb
require 'resque/status_server'

Then start resque-web with your config:

resque-web ~/resque_conf.rb

This should launch resque-web in your browser and you should see a ‘Statuses’ tab.

Resque is awesome, @defunkt needs a shout-out.

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don’t break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
