That's correct. You could at least alert on that one condition without a "nodename", in the knowledge that all other alerts *would* have a nodename. If you want to join on something always, then you have to make sure that thing exists - such as a static recording rule, or a metric which is being scraped from somewhere else, like a static http page. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
