For example if jobLabel is set to foo and the Kubernetes Service object is labeled with foo: bar , then Prometheus adds the job="bar" label to all ingested metrics. If the value of this field is empty or if the label doesn't exist for the given Service, the job label of the metrics defaults to the name of the associated Kubernetes Service . keepDroppedTargets integer Per-scrape limit on the number of targets dropped by relabeling that will be kept in memory. 0 means no limit.
