Total RAM on Server is 12 GB & if i m calculating RES then its showing 22 GB 3.7 for each thread & total 6 threads. Can any one let me know why its showing viered output.Is it a bug in OS.
in unix when i use top
i get an output like this:

I have a question about the accuracy of prstat.
I did a 'prstat -t' and it shows 99% of my memory is occupied by oracle.
NPROC USERNAME SIZE RSS MEMORY TIME CPU

However, 'top' shows I still have 7762meg of memory free.

Hello all
im working on sunos machine that dont have the top installed and can't be
install , now i need to get information similar to what top gives me about the cpu usage and so
can it be done somehow else where ? (3 Replies)
Okay, I am trying to come up with a multi-platform script to report top ten CPU and memory hog processes, which will be run by our enterprise monitoring application as an auto-action item when the CPU and Memory utilization gets reported as higher than a certain threshold

Hi Export,
i execute 'top' command to show the free memory in Solaris host, but the read is much lower than the RSS value shown in prstat command. Which one can reflect the real status and it is possible the difference caused by any patch of OS?

Hi,
Yersterday I started monitoring my homeserver memory consumition due some errors found in the system (network hangs). I've detected almost all the memory used (~10 MB free from 1GB).
First I thought it was because of the MySQL configuration, so I monitored it with top and found it wasn't... (6 Replies)
Hi guys,

free - Display amount of free and used memory in the system
SYNOPSIS
free [options]
DESCRIPTION
free displays the total amount of free and used physical and swap memory in the system, as well as the buffers and caches used by the ker-
nel. The information is gathered by parsing /proc/meminfo. The displayed columns are:
total Total installed memory (MemTotal and SwapTotal in /proc/meminfo)
used Used memory (calculated as total - free - buffers - cache)
free Unused memory (MemFree and SwapFree in /proc/meminfo)
shared Memory used (mostly) by tmpfs (Shmem in /proc/meminfo)
buffers
Memory used by kernel buffers (Buffers in /proc/meminfo)
cache Memory used by the page cache and slabs (Cached and SReclaimable in /proc/meminfo)
buff/cache
Sum of buffers and cache
available
Estimation of how much memory is available for starting new applications, without swapping. Unlike the data provided by the cache or
free fields, this field takes into account page cache and also that not all reclaimable memory slabs will be reclaimed due to items
being in use (MemAvailable in /proc/meminfo, available on kernels 3.14, emulated on kernels 2.6.27+, otherwise the same as free)
OPTIONS -b, --bytes
Display the amount of memory in bytes.
-k, --kibi
Display the amount of memory in kibibytes. This is the default.
-m, --mebi
Display the amount of memory in mebibytes.
-g, --gibi
Display the amount of memory in gibibytes.
--tebi Display the amount of memory in tebibytes.
--pebi Display the amount of memory in pebibytes.
--kilo Display the amount of memory in kilobytes. Implies --si.
--mega Display the amount of memory in megabytes. Implies --si.
--giga Display the amount of memory in gigabytes. Implies --si.
--tera Display the amount of memory in terabytes. Implies --si.
--peta Display the amount of memory in petabytes. Implies --si.
-h, --human
Show all output fields automatically scaled to shortest three digit unit and display the units of print out. Following units are
used.
B = bytes
K = kibibyte
M = mebibyte
G = gibibyte
T = tebibyte
P = pebibyte
If unit is missing, and you have exbibyte of RAM or swap, the number is in tebibytes and columns might not be aligned with header.
-w, --wide
Switch to the wide mode. The wide mode produces lines longer than 80 characters. In this mode buffers and cache are reported in two
separate columns.
-c, --count count
Display the result count times. Requires the -s option.
-l, --lohi
Show detailed low and high memory statistics.
-s, --seconds delay
Continuously display the result delay seconds apart. You may actually specify any floating point number for delay using either .
or , for decimal point. usleep(3) is used for microsecond resolution delay times.
--si Use kilo, mega, giga etc (power of 1000) instead of kibi, mebi, gibi (power of 1024).
-t, --total
Display a line showing the column totals.
--help Print help.
-V, --version
Display version information.
FILES
/proc/meminfo
memory information
BUGS
The value for the shared column is not available from kernels before 2.6.32 and is displayed as zero.
