The following recipe will show you the NUMA configuration of your VM:
- Enable SSH access to the host where your VM is running.
- SSH to the host and log in as the root.
- Find the path to the VM's log file using this command:
# vmdumper -l | grep <VM name>
- This will output the path to the .vmx file for the VM you specified.
- Now look for the information in the vmware.log for that VM (not the .vmx file), # cat /vmfs/volumes/5390c2da-b6859d14-2d39-90b11c097755/Demo/vmware.log | grep numa:
In this case, we have 16 vCPUs that are in two Virtual Proximity Domains. These correlate correctly to the two Physical Proximity Domains available on the host ESXi server.
