NAME¶

vzcalc - calculate resource usage of a container

SYNOPSIS¶

[-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.
