NAME
       vzcalc - utility to calculate the container's resources usage.

SYNOPSIS
       vzcalc [-v] CTID

OPTIONS
       -v  Display additional information.

DESCRIPTION
       This utility displays the share of the host system resources a
       particular container is using. If the container is running, the current
       usage is displayed. High utilization values (>100%) mean the system is
       overloaded (or the container has an invalid configuration).

       Current
           shows the amount of the resources consumed by the container at a
           given time.

       Promised
           shows the resources soft limit values "promised" for a given
           container.

       Max 
           shows the resources hard limit values "promised" for a given
           container.

       If the -v option is specified, the additional information is displayed.

       Low Mem
           the part of memory residing at lower addresses and directly
           accessed by the kernel.

       Total Ram
           whole RAM

       Mem+Swap
           amount of memory available for applications (both RAM and swap
           space).

       Alloc Mem
           standard memory allocations made for applications in a container.
           This is a more "virtual" system resource than RAM or RAM and swap.
