Device meta

olle

Your Grafana connector supports naming query results by device meta data. The connector docs says:

"Name by: Default the name in the graph is from the "name" field of the function, but you can use any metadata here. Try topic_read to see values by their mqtt-topic or maybe create your own metadata in Lynx, e.g. grafana_name and use that one."

Question: Is it possible to combine several meta fields in the connector to form more descriptive names?

That is not possible, but I like the idea!
The best way to do it is to create metadata on the function or device for this. I many cases we use grafana_name or friendly_name for this.

This may be possible with recent plugin + grafana versions.
There is a "display name" field on some of the panel configs.
This field is templated and if you enable the "meta as labels" option, all meta data should be accessible through the template.

I do not remember how to access them right off the bat, but it's worth looking more into.

Edit:
I managed to name the series after device_id by using
${__field.labels["device_id"]} in the display name.

You could combine several labels and static text in the display name field.
