    rules:
    - expr: |
        count without (cpu) (
          count without (mode) (
            node_cpu_seconds_total{job="node-exporter"}
          )
        )
      record: instance:node_num_cpu:sum
    - expr: |
        1 - avg without (cpu, mode) (
          rate(node_cpu_seconds_total{job="node-exporter", mode="idle"}[1m])
        )
      record: instance:node_cpu_utilisation:rate1m
