That's the "job" label. It's added automatically by prometheus, and is set to the name of the scrape job which collected the metric, as documented here: https://prometheus.io/docs/concepts/jobs_instances/
You should leave it alone. It's a true piece of information (i.e. the name of the actual scrape job which collected the data), and together with the instance label, it helps ensure that all metrics have unique sets of labels. However, you *can* customize the instance label - prometheus only adds the default address:port label if you haven't set it to anything else explicitly. See: https://www.robustperception.io/controlling-the-instance-label You have to ensure that whatever value you chose is sufficiently unique, i.e. all timeseries for the same metric have different instance labels. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
