Dear Hari,

this futile by concept, because a lightweight container is thought not own any dedicated parts of a real CPU or any other physical resource of the host, it just is a logical platform with resources to "compute", to access a "file system" or to do "networking".

You may load the "PMU driver" on the host and monitor on the host the resources used by the processes inside the container. And you may be able to setup a way to pass in the monitoring results (and/or the controll and command interface if you ignore any concerns of security) to the container.
