I have many application running on LINUX box, RAM allocated on this box is 15GB
I want to know how much memory is consumed by Applications and OS
From application level only 12 GB RAM is allocated out of it only 8 GB RAM is consumed currently
But I'm unable to figure out how much RAM is consumed by OS on an average?
If I have a margin of how much RAM is consumed to OS then in future if I need to add any new software/app I can recommend for extra RAM in LINUX BOX, hope you understand

hello
I am new to the UNIX I want to know what command is used
1.To know the Memory consumed by a process at a time .
2.To know the How many CPU's in a server.
3.To know the RAM size.
4.To know the Hard Disk size. (3 Replies)
Hello AIX gurues...
In order to present the statistics of real memory usage I need to know how much real memory is used by the AIX 5L kernel. No the exact figures of course but some close to the reality.
The AIX is running in a 7GB real machine, it has a HACMP configuration and my concern is... (1 Reply)
Hi,
I am looking for acoomand on HP where by i can see the CPU increasing for a given process ... I know i can see this from top/prstat ..
But it will give for all the processes - I want something like say ps where i can call it from a shell script a few times and check if it is has increased... (0 Replies)
Hi! I am new to HP-UX. :o
By using the command glance, I found the user memory usage was very high. I would like to know is there any command can show the process which consume most available memory ? (Just like the command top, but order by memory, not CPU) (1 Reply)
Hi!!!
how can I obtain the consumed memory of a process?
nowadays i'm using ps -efo pid, pmem, comm,args ....
but the information is in percentage, is that correct?
so, i want to know how can obtain the consumed memory of a process in mb?
thanks in advance!

I need to log the size of physical/virtual memory consumed by any given given process using c/c++ code running on solaris and aix without using the proc filesystem. Please advise. (1 Reply)
Hi,
Below is the code snippet I use on Linux (Centos) to retrieve the Process Name, PID and memory consumed on Linux (Centos) host:-
top -b -n 1 | awk -v date="$tdydate" -v ip="$ip" 'NR>7 {print date","ip","$12,","$1,","$10}'
Any idea how the same can be retrieved on an AIX host? This... (1 Reply)

ncsize
ncsize(5) File Formats Manual ncsize(5)NAME
ncsize - number of Directory Name Lookup Cache (DNLC) entries
VALUES
Failsafe
Default
Allowed values
The minimum value allowed is The maximum value allowed is memory limited. The value is further constrained in that it must be equal to or
greater than eight times the value of the number of locks for the DNLC
Specify a positive integer value.
DESCRIPTION
To speed up the search through directories in the kernel, there is a memory resident cache of directories called the During a filename
lookup in the kernel, any directories or files encountered are retained in the DNLC for future reference. The tunable dictates the number
of entries in the DNLC, which is statically allocated at system boot time. Therefore, the larger the value of the larger the number of
directory/file entries that can be kept cached in memory for filename lookup.
Who Is Expected to Change This Tunable?
HP-UX system administrators.
Restrictions on Changing
This tunable is static. Any changes to the value of this tunable will require system reboot before taking effect.
When Should the Value of This Tunable Be Raised?
The value may need to be raised to improve filename lookup performance when running applications which require large numbers of filename
access.
What are the Side Effects of Raising the Value?
More system memory will be consumed for the DNLC.
When Should the Value of This Tunable Be Lowered?
The value can be lowered to limit the number of entries in the DNLC and reduce memory consumption.
What are the Side Effects of Lowering the Value?
Less system memory will be consumed for the DNLC upon system reboot. Operations requiring filename lookup (e.g. open(2)) may experience
performance degradation.
What Other Tunable Values Should Be Changed at the Same Time?
The value of must be equal to or greater than eight times the value of
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of
HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
