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.
