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)

systemd-cryptsetup-generator
SYSTEMD-CRYPTSETUP-GENERATOR(8) systemd-cryptsetup-generator SYSTEMD-CRYPTSETUP-GENERATOR(8)NAME
systemd-cryptsetup-generator - Unit generator for /etc/crypttab
SYNOPSIS
/lib/systemd/system-generators/systemd-cryptsetup-generator
DESCRIPTION
systemd-cryptsetup-generator is a generator that translates /etc/crypttab into native systemd units early at boot and when configuration of
the system manager is reloaded. This will create systemd-cryptsetup@.service(8) units as necessary.
systemd-cryptsetup-generator implements systemd.generator(7).
KERNEL COMMAND LINE
systemd-cryptsetup-generator understands the following kernel command line parameters:
luks=, rd.luks=
Takes a boolean argument. Defaults to "yes". If "no", disables the generator entirely. rd.luks= is honored only by initial RAM disk
(initrd) while luks= is honored by both the main system and the initrd.
luks.crypttab=, rd.luks.crypttab=
Takes a boolean argument. Defaults to "yes". If "no", causes the generator to ignore any devices configured in /etc/crypttab
(luks.uuid= will still work however). rd.luks.crypttab= is honored only by initial RAM disk (initrd) while luks.crypttab= is honored
by both the main system and the initrd.
luks.uuid=, rd.luks.uuid=
Takes a LUKS superblock UUID as argument. This will activate the specified device as part of the boot process as if it was listed in
/etc/crypttab. This option may be specified more than once in order to set up multiple devices. rd.luks.uuid= is honored only by
initial RAM disk (initrd) while luks.uuid= is honored by both the main system and the initrd.
If /etc/crypttab contains entries with the same UUID, then the name, keyfile and options specified there will be used. Otherwise, the
device will have the name "luks-UUID".
If /etc/crypttab exists, only those UUIDs specified on the kernel command line will be activated in the initrd or the real root.
luks.name=, rd.luks.name=
Takes a LUKS super block UUID followed by an "=" and a name. This implies rd.luks.uuid= or luks.uuid= and will additionally make the
LUKS device given by the UUID appear under the provided name.
rd.luks.name= is honored only by initial RAM disk (initrd) while luks.name= is honored by both the main system and the initrd.
luks.options=, rd.luks.options=
Takes a LUKS super block UUID followed by an "=" and a string of options separated by commas as argument. This will override the
options for the given UUID.
If only a list of options, without an UUID, is specified, they apply to any UUIDs not specified elsewhere, and without an entry in
/etc/crypttab.
rd.luks.options= is honored only by initial RAM disk (initrd) while luks.options= is honored by both the main system and the initrd.
luks.key=, rd.luks.key=
Takes a password file name as argument or a LUKS super block UUID followed by a "=" and a password file name.
For those entries specified with rd.luks.uuid= or luks.uuid=, the password file will be set to the one specified by rd.luks.key= or
luks.key= of the corresponding UUID, or the password file that was specified without a UUID.
rd.luks.key= is honored only by initial RAM disk (initrd) while luks.key= is honored by both the main system and the initrd.
