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.
