How to display all metrics that don't have a specific label

Question

I want to select all metrics that don't have label "container". Is there any possibility to do that with prometheus query?

Answer 1

In recent versions of Prometheus it's enought to query for something like this:

node_load1{not_existent_label=""}

Answer 2

You can also try checking if the label is or isn’t equal to the empty string.

metric_name{label_name=""} 

Or, try label data integrity checks form deepchecks

All the best!
