So I have a number of fairly typical panels (CPU usage, RAM, HDD activity etc.) which show red / orange / green depending on their values. What I would like is a single panel that sits above these which combines the results of the above to give an overall “Okay” status.
E.G. If RAM is in the green, CPU is in the green and HDD activity is green, then the summary box will be green. Likewise if anything is red or amber the summary box will show red.
Ideally I want to achieve this directly inside Grafana rather than Prometheus so I can use data from difference sources.
I have tried running multiple queries in one singlestat panel, with a view to getting “1” for each individual aspect that is correct, and then summing that number to see if all are 1, but this results in the usual “multiple dataset” error for a singlestat, and would also mean repeating the query I have already written elsewhere
