Linux Ncloud Tool Kit (Linux NTK) is a tool kit for Linux VM provided on NAVER Cloud Platform. It provides various functions including server status diagnosis, disk I/O test, log collection, and system patch. These functions facilitate operation and maintenance of NCP VM and serve as a communication tool for resolving NCP VM issues.

Running Linux NTK

To run NTK on the Linux server, do the following:

1. Check the type of hypervisor being used for hosting the VM.
   The zipped NTK file name and the NTK file download link differ according to the hypervisor type.

   • XEN-based server

    [root@xen-server etc]# dmesg | grep "Hypervisor detected" | awk -F': ' '{print $2}'
    Xen HVM
   

   • KVM-based server

   [root@kvm-server etc]# dmesg | grep "Hypervisor detected" | awk -F': ' '{print $2}'
   KVM
   

2. Move to the path where the NTK file is located.

    [root@xen-server ~]# cd /usr/local/etc
   

3. Unzip the NTK file.

   • XEN-based server

   [root@xen-server etc]# tar zxvf ntk.tar.gz
   

   • KVM-based server

    [root@kvm-server etc]# tar zxvf ntk-kvm.tar.gz
   

   If no ntk.tar.gz file exists or if you wish to replace the existing file with the latest version, download the file first.

   • XEN-based server

   [root@xen-server etc]# wget -P /usr/local/etc http://init.ncloud.com/server/ntk/linux/xen/ntk.tar.gz
   

   • KVM-based server

   [root@kvm-server etc]# wget -P /usr/local/etc http://init.ncloud.com/server/ntk/linux/kvm/ntk-kvm.tar.gz
   

4. Run NTK.

   [root@xen-server etc]# /usr/local/etc/ntk/ntk
