Eric Yang commented on YARN-7829:
---------------------------------

[~GergelyNovak] Thank you for the patch.  The dashboard looks better with your 
patch.  Original proposal wasn't strictly bound to two rows, but we can have 
second row charts to auto flow base on browse width.  New charts can be added 
to fill up the empty space.  Bootstrap can specify the screen resolution to 
assist the auto flow base on media resolution, and we can probably auto-flow 
two charts to third row base on browser width.  I agree with you that if 
someone maximize browser on 16:9 TV.  The two rows to fill out the horizontal 
real estate is not helping, and we probably want to create more charts to fill 
up the empty space or increase the chart heights of second row to the same 
height as the first row. 

 

Small nits that Memory and VCore are also related to system resource, which are 
more closely related to Cluster Resource on the top row.  Would it be better to 
move Finished Apps and Running Apps to third row?  Memory-mb and Vcores 
probably need capitalization for correctness.  Thoughts?

> The cluster overview page looks like a upside down triangle.  It would be 
> nice to rebalance the charts to ensure horizontal real estate are utilized 
> properly.  The screenshot attachment includes some suggestion for rebalance.  
> Node Manager status and cluster resource are closely related, it would be 
> nice to promote the chart to first row.  Application Status, and Resource 
> Availability are closely related.  It would be nice to promote Resource usage 
> to side by side with Application Status to fill up the horizontal real 
> estates.
