In your prometheus.yml it should look like this:

yaml 
- job_name: netdata
  metrics_path: /api/v1/allmetrics?format=prometheus_all_hosts&source=raw
  relabel_configs:
  - source_labels: [__address__]
    regex: ^(.+)\.\w+:\d+
    target_label: instance
    action: replace
  static_configs:
  - targets: [netdata.hostname.here:19999]
    labels:
      env: production
      group: applications
      source: newproject
