Sure: some PromQL functions return no metric name and/or no labels. That's how those functions operate.
For example, sum(metric) doesn't return any labels, because it's summing together all the timeseries with that particular metric. Each individual metric, by definition, has a different set of labels. The sum of those metrics has no identifying labels, since it combines all those metrics. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
