NAME
       vzcalc - calculate resource usage of a container

SYNOPSIS
       vzcalc [-v] CTID

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 following additional information is
       also displayed:

       Low Mem
              The part of memory residing at lower addresses and directly
              accessed by the kernel (only makes sense for 32-bit
              architectures).

       Total RAM
              Total memory.

       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.

       Num. Proc
              Number of processes.

OPTIONS
       -v     Display additional information.

EXIT STATUS
       Normally, the exit status is 0. On error, the exit status is 1.
