Hi,
We are running Splunk on RedHat 7.x VMs and originally the VMs had 2 cpus with 2 cores each. In DMC and in REST service "| rest splunk_server=local /services/server/info" the output is that we have 4 cores in total. Recently we've upgraded the VMs to have 4 cpus and we were expecting to see that we'll have 8 cores available in total. But it doesn't seem so.
Any ideas why? We have restarted Splunkd and the whole VM. The outputs of linux commands in SSH like "lscpu" or "cat /proc/cpuinfo" show that there are 4 cpu's installed in the VM, but Splunkd still doesn't notice them...
I am experiencing identical problem. Haven't been able to find answer online nor get in contact with Splunk support. Splunk isn't noticing my extra cores after I upgraded instance. Now I'm having performance issues like hot buckets rolling prematurely and the speed of concurrent searches is suffering.
