# vzcalc(8)

calculate resource usage of a container

## 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.
