NAME[edit]
vzcalc − calculate resource usage of a container
SYNOPSIS[edit]
|
vzcalc |
[-v] CTID |
DESCRIPTION[edit]
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[edit]
|
-v |
Display additional information. |
EXIT STATUS[edit]
Normally, the exit status is 0. On error, the exit status is 1.
