How to identify ip address for instance in Prometheus Query result?

1

I’ve a docker swarm configured with nodeA as manager and nodeB as worker and have Promethues and Grafana installed as docker container on nodeA with prometheus.yml file as -

global:
  scrape_interval: 10s
scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets:
        - 'localhost:9090'

  - job_name: 'node resources'
    dns_sd_configs:
      - names: ['tasks.node']
        type: 'A'
        port: 9100
    params:
      collect[]:
        - cpu
        - meminfo
        - diskstats
        - netdev
        - netstat

  - job_name: 'node storage'
    scrape_interval: 1m
    dns_sd_configs:
      - names: ['tasks.node']
        type: 'A'
        port: 9100
    params:
      collect[]:
        - filefd
        - filesystem
        - xfs

  - job_name: 'cadvisor'
    dns_sd_configs:
      - names: ['tasks.cadvisor']
        type: 'A'
        port: 8080

In Prometheus/Grafana, if I execute query - container_cpu_usage_seconds_total it gives results like -

✔container_cpu_usage_seconds_total{cpu="cpu15",id="/user.slice",instance="10.0.1.220:8080",job="cadvisor"}
✔container_cpu_usage_seconds_total{cpu="cpu15",id="/user.slice",instance="10.0.1.219:8080",job="cadvisor"}

I can see instance having values 10.0.1.219:8080 and 10.0.1.220:8080 but these are not ip addresses of machines in swarm.

How can I differentiate which instance is for which machine? Is there something which I should configure?
