absent_over_time(...) produces labels in some circumstances, but not in others: https://prometheus.io/docs/prometheus/latest/querying/functions/#absent_over_time
I presume your expression is also one that has no labels, because otherwise the "OR" condition wouldn't work. Anyway, this seems to work: label_replace(vector(0), "foo", "bar", "__name__", ".*") Or maybe a recording rule is cleaner. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
