node exporter: cpu count metric?

[Kris Budde]

Hi,

I was looking for the number of cpus for each node as some metrics are more meaningfull if compared to number of processors.

e.g. cpu load or context switches.

I know I can calculate the number of cpu cores, e.g. "count(count(node_cpu_seconds_total{instance=~"$node"}) without (mode,instance,job)) without (cpu) "

Is there really no metric? In this case I'm going to create a feature request.

Best regards

No, it is explicit that there is no count metric, as it can be derived.

See the example recording rule:
