I use OSS Graphana 9.2.1 together with Influx DB version that is higher than 2 (that uses Flux instead of SQL).
I have a publish dashboard that is streaming to a number of kiosks. It shows some gauges and refreshes every 30 seconds.
I’d like to add a simple filed (panel) to this dashboard in order to indicate that a kiosk received the latest data and no freeze is there. I think that it could be a current time received from server or something like a time that is passed from the latest refresh.
Looking into the documentation I found out that a panel with type Singlestat can help me with this. So I’ve added such a plugin (updated) Singlestat to Graphana but later I wasn’t succeed at all.
How can I get the latest refresh or at least the system time from Graphana or Flux and put it into this SInglestat panel.
All the tutorials found over Internet are just about the old and non available Singlestat plugin. So I need some help here with this beast.
