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.
