Status of a monitor

Hello!

I am new in this software.
I am using nagios to get status and performance data.
Now I want to build a system-overview-dashboard. One panel should be the diskstate!

I want to get a list with all Servers where the servicestate of the Counter “Diskspace” is in Warnig or Critical.
If this is not possible I want to get a list of all servers with the state of “Diskspace”.
It would be nice to see the value also!
I want to build a query that give me the state of an service back (1,2,3 or 4)

How can I do this?

Depends on what your time series database is and how the data is stored in that database.
