NUMACC will indicates following information:

1. Which CPU core that process runs on.
2. Whether this process is pin to certain CPU core or not.
3. NUMA node of net devices for given container/pod.

Allowing user to know if the container/pod is under proper NUMA configuration.

Requirement

go v1.10

Installation

git clone https://github.com/mjace/numacc
cd numacc
go get -d ./...
./numacc

Usage

To check NUMA configuration of container

./numacc cid <1234ABCFD>

Example
