cp prom.conf.sample ranger-admin.conf

Adjust the content of ranger_admin.conf as follows:

  urls = ["http://localhost:17143/metrics"]
  source ="ranger-admin"
  [inputs.prom.tags]
    component = "ranger-admin" 
  interval = "10s"

Other configurations should be adjusted as needed, parameter adjustment description:

• urls: The jmx-exporter metrics address, fill in the metrics url exposed by the corresponding component here.
• source: Collector alias, it is recommended to make distinctions.
• keep_exist_metric_name: Keep metric names.
