Using grafana 10.2.2 and Grafana Status panel 2.0.0
I do realize that postgresql is not among the listed data sources for the Grafana status panel, so it might be that is the reason it is not working.
I have a postgresql query that gives me three fields: A service name (string) a parameter for the service(float) and a timestamp. When I try to set this up for a Grafana Status Panel, I just get a green field with the annotation “A - invalid number” I would expect to be able to set it up to have one square per service that could be set up to display different colors depending on the value of the parameter.
