Jobs and instances

For example, an API server job with four replicated instances:

• job:
  • instance 1: 1.2.3.4:5670
  • instance 3: 5.6.7.8:5670
  • instance 4: 5.6.7.8:5671

• : The configured job name that the target belongs to.

If either of these labels are already present in the scraped data, the behavior depends on the honor_labels configuration option. See the for more information.

• up{job="<job-name>", instance="<instance-id>"}: if the instance is healthy, i.e. reachable, or 0 if the scrape failed.
• scrape_duration_seconds{job="<job-name>", instance="<instance-id>"}: duration of the scrape.
• scrape_samples_post_metric_relabeling{job="<job-name>", instance="<instance-id>"}: the number of samples remaining after metric relabeling was applied.
• : the approximate number of new series in this scrape. New in v2.10

The up time series is useful for instance availability monitoring.
