[horizon][dev] Auto-Refresh Feature Proposal

I am sorry, but I can't speak for the horizon team (I primarily work
on Octavia and Designate). That said, in the OpenStack community
contributions are always welcome.
I know there has been a discussion about working on a new dashboard
project called skyline, so I would recommend having a discussion
with the horizon team before investing a lot of time on the current
code base. That said, I would expect a blueprint and/or specification
would mostly apply to both projects.
The link you provided is for a deployment project "OpenStack Charms"
and is likely not the process that the horizon team uses.
Horizon has a developer guide here:
This includes a section on creating a new feature for horizon.
I would recommend creating the blueprint and even the specification to
get the discussion started if you are not getting a timely response on
the email list.

As you may know, Horizon requires the user to manually update the page in order to get the most recent data in the system, e.g. if an instance is created, deleted or renamed before the page is reloaded, the user has to hit the refresh button in their browser to see those changes in the page. This applies to the majority of Horizon's pages, including, but not limited to, Instances, Volumes, Users and so on.

We've been using it for a while now and have received positive feedback from our clients. It automatically updates the information in tables, pie charts (such as the Compute Overview page graphs) and details pages every five seconds, without the need for manually refreshing the page. The information displayed on the page will be replaced by the most recent data without any action from the user or any page reloading. It essentially works by requesting, in the background, the opened page again and again every few seconds through AJAX, and then replacing the old information with the new one if they differ. The feature affects every element in Horizon, except AngularJS ones - the tables in the Compute Images, Key Pairs and Server Groups pages are AngularJS elements and will not be affected by auto-refresh, for example. We are open to looking into this issue in the future, though.
