[wildfly-dev] Domain Overview design

[Liz Clayton]

Hi, 

I'm sketching out some ideas for the Domain Overview screen. I'd like to find a visualization that make it easier to scan the page to determine server availability, and possibly alerts.  

Given that the domain could be large, the visualization needs to scale. I started by looking at heatmap visualizations, which worked pretty well. Although I didn't feel like they helped in describing the overall relationships of servers, server groups and hosts... So I decided to break the heat maps into individual (stacked) heatmaps, ordered by server group. My hope is that this helps to define groupings and such. 

I posted the current design proposal at:
https://community.jboss.org/wiki/DomainOverview070114pdf

It would be great to get feedback on the designs. Some questions I have are:
- Is it difficult/easy to understand that the boxes, in the server groupings, are intended to represent servers?
- Should the servers be laid out in the visualization by level of availability/status (as illustrated), or by some other ordering (A-Z, Z-A...)?
- Is it difficult/easy to understand that when a box is a different color, that it is indicating its availability status? 
- What do you expect to be the relationship between (Availability) Status and Alerts? Would “x” alerts equate to a change in availability status, or can they function independently? For example: Could you have an error on a server and it still be “available?”

Thanks,
Liz
