vzcalc - calculate resource usage of a container
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.
- -v
- Display additional information.
Normally, the exit status is 0. On error, the exit status is 1.
