Node Status Summary Resource/Widget. To create:
1) Edit the Summary Page you are on
2) Add Widget --> Custom Query
3) Save the page
4) Edit the Custom Query Resource/Widget
5) Change the name to "Node Status Summary", and use the following query:
select case Status
when 1 then 'UP'
when 2 then 'DOWN'
when 3 then 'WARNING'
when 11 then 'External'
when 14 then 'Critical'
else 'Other' end as Current_State,
Count(Status) as Number
from Orion.Nodes group by Status order by Status
6) Submit, and voila! You should have something similar to the picture posted here.
I will work on making this prettier if I can later. I'll edit this post if/when I do.
