Please, take a look at prometheus documentation for scrape_config - https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config

VMagent uses same format for config as described here - https://docs.victoriametrics.com/vmagent.html#how-to-collect-metrics-in-prometheus-format

Default value for this variable is:

vmagent_scrape_config:
  scrape_configs:
    - job_name: localhost
      static_configs:
        - targets: []
#          - "127.0.0.1:9100"

Where you will need to add your jobs and respective targets to scrape_configs section.
