I'm using top to view processes. But, I do not know how to scroll down the list to view what is not showed in the terminal window. Anyone know how to do this? (1 Reply)
Hi all,
I found like top command could be used to find the Memory and CPU utilization. But i want to know how to find the Memory and CPU utilization for a particular user using top command.
Thanks in advance.

I m using following command to find top 10 cpu consuming processes.
However whenever i execute the command i get
following warning.
What can be done to avoid it?
# ps -auxf | sort -nr -k 3 | head -10
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.7/FAQ

Hi all,
Is it possible to get total memory usage and free memory usage without top? By Googling I found for total memory usage, use vmstat, for CPU, use mpstat, for disk I/O use iostat, is this correct? Will using sar gives the same result as ALL of these three (3) commands?
What about if I... (2 Replies)
ps -eo pid,comm,%cpu lists all processes (in increasing PID number).
How to get only the top-10 most CPU intensive ones? I know about top: this is BASH exercise.
I tried redirecting above code to cut ps -eo pid,comm,%cpu | cut -f2but ps' output isn't TAB delimited. How can I otherwise use... (5 Replies)
When I run 'top' command,I see the following
Memory: 32G real, 12G free, 96G swap free
Though it shows as 12G free,I am not able to account for processes that consume the rest 20G.
In my understanding some process should be consuming atleast 15-16 G but I am not able to find them.

systemd-cgtop
SYSTEMD-CGTOP(1) systemd-cgtop SYSTEMD-CGTOP(1)NAME
systemd-cgtop - Show top control groups by their resource usage
SYNOPSIS
systemd-cgtop [OPTIONS...]
DESCRIPTION
systemd-cgtop shows the top control groups of the local Linux control group hierarchy, ordered by their CPU, memory, or disk I/O load. The
display is refreshed in regular intervals (by default every 1s), similar in style to top(1). If systemd-cgtop is not connected to a tty,
only one iteration is performed and no columns headers are printed. This mode is suitable for scripting.
Resource usage is only accounted for control groups in the relevant hierarchy, i.e. CPU usage is only accounted for control groups in the
"cpuacct" hierarchy, memory usage only for those in "memory" and disk I/O usage for those in "blkio". If resource monitoring for these
resources is required, it is recommended to add the CPUAccounting=1, MemoryAccounting=1 and BlockIOAccounting=1 settings in the unit files
in question (See systemd.resource-control(5) for details).
To emphasize this: unless "CPUAccounting=1", "MemoryAccounting=1" and "BlockIOAccounting=1" are enabled for the services in question no
resource accounting will be available for system services and the data shown by systemd-cgtop will be incomplete.
OPTIONS
The following options are understood:
-h, --help
Prints a short help text and exits.
--version
Prints a version string and exits.
-p
Order by control group path name.
-t
Order by number of tasks in control group (i.e. threads and processes).
-c
Order by CPU load.
-m
Order by memory usage.
-i
Order by disk I/O load.
-b, --batch
Run in "batch" mode: do not accept input and run until the iteration limit set with --iterations is exhausted or until killed. This
mode could be useful for sending output from systemd-cgtop to other programs or to a file.
-n, --iterations=
Perform only this many iterations.
-d, --delay=
Specify refresh delay in seconds (or if one of "ms", "us", "min" is specified as unit in this time unit).
--depth=
Maximum control group tree traversal depth. Specifies how deep systemd-cgtop shall traverse the control group hierarchies. If 0 is
specified, only the root group is monitored. For 1, only the first level of control groups is monitored, and so on. Defaults to 3.
KEYS
systemd-cgtop is an interactive tool and may be controlled via user input using the following keys:
h
Shows a short help text.
SPACE
Immediately refresh output.
q
Terminate the program.
p, t, c, m, i
Sort the control groups by path, number of tasks, CPU load, memory usage, or IO load, respectively.
%
Toggle between showing CPU time as time or percentage.
+, -
Increase or decrease refresh delay, respectively.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
