 Single-node VictoriaMetrics and [vmagent](https://docs.victoriametrics.com/vmagent.html) automatically add `instance` and `job` labels per each discovered target:
 
 * The `job` label is set to `job_name` value specified in the corresponding [scrape_config](https://docs.victoriametrics.com/sd_configs.html#scrape_configs).
