There are two different metrics you are looking at. (1) "up" says whether the scrape was successful - i.e. prometheus was able to communicate with blackbox_exporter and read the response
(2) "probe_success" is one of the metrics returned from blackbox_exporter, saying whether it was able to talk to the target or not So if blackbox_exporter is working, but the target is down, you will get up=1 and probe_success=0. If you kill blackbox_exporter, then you will get up=0 In terms of the two GUIs you showed: the blackbox_exporter is showing you "probe_success", but prometheus is showing you "up". "up" is a special metric for prometheus: its one that it generates itself, so the prometheus GUI knows that it exists and gives it special treatment. "probe_success" is a metric which happens to be returned by blackbox_exporter. The prometheus GUI doesn't give this any special treatment because it's just a metric like any other. But if you go into the query page of prometheus and type "probe_success" as the promQL query, you'll see what you are looking for. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
