vzcalc(8)							    Containers								 vzcalc(8)

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.
