count without (cpu, mode) (node_cpu_seconds_total{mode="system"}))
is one way of counting the number of CPUs on a server, so:
(node_load5 / count without (cpu, mode)
(node_cpu_seconds_total{mode="system"})) > 1
would alert you when the (5 minute) load average is greater than the number of
CPUs.
I find this alert to be noisy - your experience may differ.
