无法在 Grafana 仪表板上看到节点的数据

Question

I have installed Prometheus and Grafana on my Ubuntu. I have added node exporter to scrape metrics. In the Grafana, I added Prometheus as my data source. It got added successfully. However, when I import Node Exporter Dashboard, I do not get any data. What can be the issue? Here is my Prometheus Job configuration.

global:
  scrape_interval: 10s

scrape_configs:
  - job_name: 'prometheus_metrics'
    scrape_interval: 5s
    static_configs:
      - targets: ['localhost:9090']
  - job_name: 'node_exporter_metrics'
    scrape_interval: 5s
    static_configs:
      - targets: ['localhost:9100', '192.168.10.42:9100']

Here is the grafana log output.

level=error msg="Internal server error" error="[plugin.downstreamError] failed to query data: received empty response from prometheus"
