How to get node exporters metrics from Prometheus database without connecting to exporters explicitly

Hello experts-
Requirement is to create a Kibana dashboards of OS related metrics by reusing Prometheus Server setup.

  1. I am having a Prometheus server and multiple node exporters (30) already set up in AWS.
  2. Installed metric beat on Prometheus server and integrated with Elasticsearch
  3. Now I want to retrieve exporters (Targets) metrics which is already stored in Prometheus at regular interval .
  4. Metricbeat document is suggesting to connect with each host (Node Exporters) explicitly and scrape the data ,which is not feasible in my case . I want to avoid making multiple calls to other servers . Dont want to increase traffic.

Please suggest a way to get data directly all the exporter metric from Prometheus Server.

Many Thanks
