Only sort of. The kernel will readily give up cache when needed. Large amounts of cache show a system that's not currently under memory pressure, but could be doing a fair amount of I/O. Large amounts of swap show a system that was under memory pressure at some point in the past but may not be now. Stuff that ends up in swap tends to stay, since idle memory gets swapped, not busy memory; it'll leave swap when asked for and no sooner.

vzcalc
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.
