Operating Systems Linux Red Hat Concept of free –m command in Linux Post 302822707 by RHCE on Tuesday 18th of June 2013 05:20:32 AM

Thanks for your answer. Does it mean that if it is a 64 bit kernel, it could use even 40 GB if the laptop has that much memory? Also, does it mean that a PAE kernel would use maximum of 64 GB of memory even if the laptop/ machine had 128 GB of memory?

I hope my queries are clear that

1) A 64 bit kernel would use even upto 40 GB of memory if I increased the laptop memory to 40 from 8 GB.
2) A PAE kernel would use only 64 GB of memory even if the laptop/machine had 128 GB of memory.

Request you to please revert.

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. LICENSE
