This tutorial walks you through setting up Nomad monitoring pipeline using Prometheus publisher, Telegraf metrics collector, InfluxDB as time series database and Grafana for visualisation.

Metrics Flow

Nomad -> Telegraf -> InfluxDB

Configs

• Nomad
  • Telemetry should be enabled with Prometheus metrics:

  telemetry {
    publish_allocation_metrics = true
    publish_node_metrics       = true
    prometheus_metrics         = true
  }

• Telegraf
  • Prometheus input:

  [[inputs.prometheus]]
  urls = ["http://{{NOMAD_NODE_ADDRESS}}:4646/v1/metrics?format=prometheus"]

• Grafana dashboards
  • Grafana.com Dashbords
  • Example Nomad jobs with pre-configured data sources and dashboards
