Notes

• There is an example of utilizing node-exporter for scraping host level metrics.
  This requires node-exporter be setup on the target host. By default it is setup on
  port 9100. The grafana dashboard will report No data for some panels if not used.
  See: https://github.com/prometheus/node_exporter for more details.

• To view all metrics associated with a job, browse to http://localhost:9090/graph and search
  for the job in question.

  • i.e: {job="node"}
  • i.e: {job="node-exporter"}

• Dashboard can be updated by modifying ./monitoring/grafana/dashboards/casper-dashboard.json
  and restarting the containers.
