Command to check memory used or consumed by OS kernel

I am trying to check how much memory is consumed by OS Kernel using below command, Is this the correct command that I'm using

Code:
grep Slab /proc/meminfo

Output : Slab: 3106824 kB
IF I convert KB to GB, It means 2.9 GB of RAM is consumed


Below details for reference
Code:
  uname -a (6.8 santiago)
2.6.32-696.1.1.el6.x86_64 #1 SMP Tue Mar 21 12:19:18 EDT 2017 x86_64 x86_64 x86_64 GNU/Linux

VIRT-CONVERT(1) 					   Virtual Machine Install Tools					   VIRT-CONVERT(1)

NAME
virt-convert - convert virtual machines between formats SYNOPSIS
virt-convert [OPTION]... INPUT.VMX|INPUT-DIR [OUTPUT.XML|OUTPUT-DIR] DESCRIPTION
virt-convert is a command line tool for converting virtual machines from one format to another. Pass in either a VM definition file (such as VMWare vmx format) or a directory containing a VM. By default, a new VM definition file, and converted disk images, will be placed in a new output directory. If an output directory is specified, it will be created if necessary, and the output VM definition placed within, along with any disk images as needed. If an output VM definition file is specified, it will be created alongside any disks in the same directory. OPTIONS
Any of the options can be omitted, in which case virt-convert will use defaults when required. An input VM definition or containing directory must be provided. By default, an output directory is generated based upon the name of the VM. The default input format is VMWare vmx, and the default output format is a libvirt "image" XML definition (see virt-image(5)). -h, --help Show the help message and exit Conversion Options -i format Input format. Currently, "vmx", "virt-image", and "ovf" are supported. -o format Output format. Currently, "vmx" and "virt-image" are supported. -D format Output disk format, or "none" if no conversion should be performed. See qemu-img(1). Virtualization Type options Options to override the default virtualization type choices. -v, --hvm Create a fully virtualized guest image Convert machine to a hvm/qemu based image (this is the default if paravirt is not specified) -p, --paravirt Create a paravirtualized guest image Convert machine to a paravirt xen based image General Options General configuration parameters that apply to all types of guest installs. -a ARCH, --arch=ARCH Architecture of the virtual machine (i686, x86_64, ppc). Defaults to that of the host machine. --os-type=OS_TYPE Optimize the guest configuration for a type of operating system (ex. 'linux', 'windows'). This will attempt to pick the most suitable ACPI & APIC settings, optimally supported mouse drivers, virtio, and generally accommodate other operating system quirks. See virt-install(1) for valid values. --os-variant=OS_VARIANT Further optimize the guest configuration for a specific operating system variant (ex. 'fedora8', 'winxp'). This parameter is optional, and does not require an "--os-type" to be specified. See virt-install(1) for valid values. --noapic Override the OS type / variant to disables the APIC setting for fully virtualized guest. --noacpi Override the OS type / variant to disables the ACPI setting for fully virtualized guest. Miscellaneous Options -q, --quiet Avoid verbose output. -d, --debug Print debugging information EXAMPLES
Convert a paravirt guest from "image.vmx": # virt-convert --arch=i686 --paravirt image.vmx Convert a 64-bit hvm guest: # virt-convert --arch=x86_64 vmx-appliance/ hvm-appliance/ AUTHOR
