Physical CPU cores & Logical CPU cores Information

Dear All,

How to obtain the physical/logical cores of each host/VM to make a report?

Regards,

Babar Qayyum

Hi,

Maybe using DQL, it was discussed in this thread.

Best regards

@Babar_Qayyum You can try the Monitored entities API and extract fields properties.cpuCores and properties.logicalCpuCores

Hi @Babar_Qayyum
you can use this script and send result as metrics:

you should recive csv like this:
