The "Vcpu" meter in the ceilometer meter-list tells you about the number of Vcpu's assigned to that instance. How can we find the number of Vcpu's the instance is using at the moment.

For example: If I create an instance and assign it 5 Vcpu's how can I check the number of Vcpus the instance is using at the moment.

Kindly provide some information on this.

CPU:s being currently used is very ambiguous thing. It can change many times in second and wont really give any usefull information. Over few seconds you might have moments when all cpus are in use and moments when none of them is really getting used.

I believe you are looking for cpu (CPU time used) and cpu_util (Average CPU utilization) meter have you taken a look at this table ?

Hi Omar,

I am not looking at the CPU utilization. Basically what I want is the count of Vcpus that are currently used. For example : a number like 2 or 3 if an instance is assigned 5 Vcpus and it is using 2 or 3 currently.
