Panoptic

Panoptic is a web interface for the SolidQueue queuing backend.

While MissionControl is getting ready for release, this gem offers a visual interface for testing purposes with SolidQueue.

Installation

Add this line to your application's Gemfile:

gem "panoptic"

Then mount the engine in your config/routes.rb file

mount Panoptic::Engine => "/panoptic"

Development

Panoptic requires Node installed to function properly in development. After cloning the repo, run:

$ bundle install
$ yarn

This will install the required Ruby and Javascript dependencies to run the project in development.

The Panoptic UI is accessible after running:

$ bin/dev

This will:

• Start the dummy app server
• Enable asset compilation in development
• Run SolidQueue

After starting the processes, access the UI at:

http://localhost:3000/panoptic

Assets

CSS

Panoptic uses Bootstrap 5 for its styles. For ease of integration, Bootstrap's Sass is compiled and checked out in version control locally. This removes the dependency on NodeJS for host applications.

New CSS must be added to the app/assets/stylesheets/panopitc directory. If your run the UI through the bin/dev command above, changes to the files in assets will be automatically picked up and compiled in the main stylesheet located at app/assets/builds/panoptic/application.css. Otherwise, the yarn build:css command needs to be run to reflect changes in CSS.

Javascript

Panoptic uses esbuild to compile its Javascript code. Javascript code is located in the app/assets/javascripts/panoptic folder.

Usage

Once the gem is installed and the Engine mounted, visit your engine route to access Panoptic. Three main views are available:

• Processes: display of the running worker and dispatcher process
• Queues
• Jobs: a list of SolidQueue jobs, with filters for scheduled and failed jobs

Current feature set:

• Retry jobs from the failed jobs panel
