Setup VictoriaMetrics cluster  

Example hosts file:

    [victoriametrics:children]
    vmstorage
    vminsert
    vmselect
    vmauth
    vmagent

    [vmstorage]
    vm-1 
    vm-2
    vm-3
    
    [vminsert]
    vm-1 
    vm-2
    vm-3
    
    [vmselect]
    vm-1 
    vm-2
    vm-3
    
    [vmauth]
    vm-1 
    vm-2
    vm-3
    
    [vmagent]
    vm-1 
    vm-2
    vm-3

Example group_vars:

    victoriametrics_vmauth_reloadAuthKey: reload-auth-key
    victoriametrics_vmauth_users:
      - id: "1"
        username: "foobar"
        password: "foobar"

    victoriametrics_vmagent_prometheus_config:
      global:
        scrape_interval: '1m'
        scrape_timeout: '1m'
      scrape_configs:
      - job_name: 'rgw'
        stream_parse: true
        static_configs:
          - targets: ['127.0.0.1:9242']
