I am running Prometheus and Grafana on docker-swarm.

  • Ubuntu16.04
  • Docker 17.09.0 ce
  • Prometheus 2.0.0 (prom/prometheus)
  • Grafana 4.6.2 (grafana/grafana)

You should not add the node exporter but the prometheus server. Sure you have the right port to prometheus?

What do you mean I should not use node-exporter?

  • node-exporter is Prometheus exporter for machine metrics, I run it with Docker as well.
  • The Docker image is here

I am sure I am using the port for the endpoint(node-exporter).

  • Save & Test is saying Data source is working meaning I am using the right port.
  • You can see Prometheus target node-exporter is up on the port in the second screenshot.

Node exporter is the collector, the address you specify in grafana should be prometheus (usually port 9090 i think)

Sorry, I am very new at Grafana and Prometheus .

As my understanding, Prometheus use pull method to collect metrics from Prometheus exporter and I assume that Grafana also just can pull the Prometheus exporter itself by registering Prometheus type data source the same as Prometheus Server.

However, you seem to be saying that I should set data source URL as Prometheus Server itself.
I did try but It seems to scrape only prometheus(localhost:9090) endpoint metrics but node_exporter(node_exporter:9100) endpoint (Please refer the below Prometheus config), is it right?

    scrape_interval: 5s
        monitor: 'my_monitor'

    - job_name: 'prometheus'
          - targets: ['localhost:9090']

    - job_name: 'node_exporter'
          - targets: ['node_exporter:9100']
