ExqUi

ExqUI provides a UI dashboard for Exq, a job processing library compatible with Resque / Sidekiq for the Elixir language. ExqUI allow you to see various job processing stats, as well as details on failed, retried, scheduled jobs, etc.

Maintainers Needed

We are seeking maintainers for this project. If you are interested in contributing as lead of co-maintainer, please reach out. See #58.

Getting Started:

See Exq for using the Exq library. This assumes you have an instance of Redis.

Installation:

Add exq_ui to your mix.exs deps (replace version with the latest hex.pm package version):

  defp deps do
    [
      # ... other deps
      {:exq_ui, "~> 0.11.0"}
    ]
  end

Then run mix deps.get.

Make sure to load exq_ui

  def application do
    [mod: {OperationSpectrum, []},
     applications: [
      :phoenix,
      # ... other deps
      :phoenix_ecto,
      :postgrex,
      :exq,
      :exq_ui
    ]
  ]
  end

For Elixir 1.2 or older, you will need to use Exq version 0.7.2 in hex, and you will also need to add :tzdata to your application list.

Configuration:

By default, Exq will use configuration from your config.exs file. You can use this to configure your Redis host, port, password, as well as namespace (which helps isolate the data in Redis).

config :exq,
  host: "127.0.0.1",
  port: 6379,
  password: "optional_redis_auth",
  namespace: "exq",
  concurrency: :infinite,
  queues: ["default"],
  poll_timeout: 50,
  scheduler_poll_timeout: 200,
  scheduler_enable: true,
  max_retries: 25

There are also a few configuration options for the UI:

config :exq_ui,
  web_port: 4040,
  web_namespace: "",
  server: true

The webport configures which port to start the UI on, and the web_namespace configures what to use as the application root (both when using mix exq.ui).

By default the empty namespace is used, so you can access the UI via: http://localhost:4040/.

When setting a different web_namespace, for example exq_ui, you can access the UI via: http://localhost:4040/exq_ui.

The server option allows you to refrain from starting the web server during tests. It is set to true by default.

Web UI:

This is a screenshot of the UI Dashboard provided by Exq UI:

To start the web UI:

> mix exq.ui

Using with Plug

To use this with Plug, edit your router.ex and add this section:

...

  pipeline :exq do
    plug :accepts, ["html"]
    plug :fetch_session
    plug :fetch_flash
    plug :put_secure_browser_headers
    plug ExqUi.RouterPlug, namespace: "exq"
  end

  scope "/exq", ExqUi do
    pipe_through :exq
    forward "/", RouterPlug.Router, :index
  end

Questions? Issues?

For issues, please submit a Github issue with steps on how to reproduce the problem.

Contributions

Contributions are welcome. Tests are encouraged.

By default, a static distribution of the UI is used. To run the UI and automatically build the JS distribution on changes, run:

> cd priv/ember
> npm install
> bower install
> ./node_modules/ember-cli/bin/ember server

To run tests / ensure your changes have not caused any regressions:

mix test --no-start
