**NUMA Configuration Checker for Container**  

NUMACC is a golang-based tool to check CPU affinity and NUMA configuration for containers and pods.  

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  

```shell script

git clone https://github.com/mjace/numacc

cd numacc

go get -d ./...

./numacc

```

## Usage 

To check NUMA configuration of container  

```shell script

./numacc cid <1234ABCFD>

```

## Example

```shell script

./numacc cid 6131f8f8cc
