Before VM, free memory was gold, but in VM it is an accident of exiting programs. RAM may be unfreed but instantly available, mapped but unmodified relative to the backing disk. You need more RAM if you cannot tune the apps and data to run with what you have fast enough. VM apps with dynamic libs share RAM, for instance. A reduces variety of apps on a system releases memory. If the apps on a specific server work on a subset of all data, that reduces RAM churn.

Hello,
in one default UFS filesystem we have 8K block size (bsize) and 1K fragmentsize (fsize). At this scenary I thought all "FileSytem IO" will be 8K (or greater) but never smaller than the fragment size (1K). If a UFS fragment/blocksize is allwasy several ADJACENTS sectors on disk (in a ... (4 Replies)

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.
