Why doesn't splunk recognize our second CPU?

All our search heads have dual processors in them but Splunk seems to only recognizes one in each of the three servers based on the number of CPU cores it reports in the Monitoring Console web gui, can Splunk use more than one processor?

Yes Splunk's Minimum search head specification's are:

An x86 64-bit chip architecture.
16 physical CPU cores, or 32 vCPU at 2Ghz or greater speed per core.
12GB RAM.

thank you, but I don't follow, you shared the minimum specifications and my question was why Splunk does not see the second CPU in our machines, I followed that link and don't see how to engage the other CPU, what am I missing?

Is it a x86 64-bit chip?

Is it hyperthreaded? Hyper-threading does not add cores as far as Splunk is concerned.

Can you check what there is added to splunkd.log when splunk has started? There should be that and another information like OS etc. mentioned.
