How to display a time string ? unsupported mean iterator typ: *query.stringInterruptItereator

Hello,

I use grafana v12.1.1. I want to display a time, how can I do that ? I get a time (for example “14:02:00”) from a logger which sents data over mqtt and it is stored in a influxdb data base. Sometines sending stops and I want to check that with the sent time of the last transmission. The logger sends the logging time every minute. I tried the clock addon, but this only shows the current time of the system. I tried to use a gauge and then I got the error message:

unsupported mean iterator typ: *query.stringInterruptItereator

How can I solve that ? Thank you!

Use more suitable panel type, e.g. table panel:

thank you! how can I add the options shown in your screenshot? Scenario, drop ?

sorry I have no experience with that

Don’t format it as timeseries, just table.

thanks, it works,

how can I display this nicer? Like a normal clock view ? Or only one column ? the view from the clock plugin would be nice.

At the moment it looks like this:

Use Transformation, e.g. Organize and “disable” columns, which you don’t need.

Play with other panel types (it was query error, not panel error) and panel options to have “nicer” look. IMHO is “normal clock view” is terrible, but you are boss of your visualizations.

this is a good solution for me, thank you!
