I have written a script that will calculate CPU usage and Memory usage of a particular process on AIX Unix. I know the PID and I am using the command --
# for CPU Usage
MSG_CPU_USG=`ps uax | grep ${PID} | awk {'print $3'}`
#for Memory Usage

Good afternoon! Im new at scripting and Im trying to write a script to
calculate total space, total used space and total free space in filesystem names matching a keyword (in this one we will use keyword virginia). Please dont be mean or harsh, like I said Im new and trying my best. Scripting... (4 Replies)
Hi,
How can I find total CPU usage in percentage? e.g. if my system has 8 CPUs and I want to list total usage for all of them, is it possible through a command?
I have tried some of the commands like top, mpstat, sar. The output of those commands has to be manipulated to derive the percentage... (14 Replies)
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)
Hi all
Can anyone advise/confirm whether total CPU usage when running sar is %user+%system+%iowait or is it %user+%system only?
I want to confirm whether I am having a CPU-bound problem or not.
This is a single-CPU VMware machine.

hi, i am using solaris server. I want to find the total CPU usage on a server. Top command will give that result, but here that command is not working. So anyone can help me to find the total CPU usage. (2 Replies)
Hi All,
I have a script which does report the cpu usuage, there are few output parameter/fields displayed from the script. My problem is I have monitor the output and decide
which cpu number (column 2) has maximum value (column 6).
Since the output is displayed/updated every seconds, it's very... (1 Reply)

sys::statistics::linux::cpustats
Sys::Statistics::Linux::CpuStats(3pm) User Contributed Perl Documentation Sys::Statistics::Linux::CpuStats(3pm)NAME
Sys::Statistics::Linux::CpuStats - Collect linux cpu statistics.
SYNOPSIS
use Sys::Statistics::Linux::CpuStats;
my $lxs = Sys::Statistics::Linux::CpuStats->new;
$lxs->init;
sleep 1;
my $stats = $lxs->get;
Or
my $lxs = Sys::Statistics::Linux::CpuStats->new(initfile => $file);
$lxs->init;
my $stats = $lxs->get;
DESCRIPTION
Sys::Statistics::Linux::CpuStats gathers cpu statistics from the virtual /proc filesystem (procfs).
For more information read the documentation of the front-end module Sys::Statistics::Linux.
CPU STATISTICS
Generated by /proc/stat for each cpu (cpu0, cpu1 ...). cpu without a number is the summary.
user - Percentage of CPU utilization at the user level.
nice - Percentage of CPU utilization at the user level with nice priority.
system - Percentage of CPU utilization at the system level.
idle - Percentage of time the CPU is in idle state.
total - Total percentage of CPU utilization.
Statistics with kernels >= 2.6.
iowait - Percentage of time the CPU is in idle state because an I/O operation
is waiting to complete.
irq - Percentage of time the CPU is servicing interrupts.
softirq - Percentage of time the CPU is servicing softirqs.
steal - Percentage of stolen CPU time, which is the time spent in other
operating systems when running in a virtualized environment (>=2.6.11).
METHODS
new()
Call "new()" to create a new object.
my $lxs = Sys::Statistics::Linux::CpuStats->new;
Maybe you want to store/load the initial statistics to/from a file:
my $lxs = Sys::Statistics::Linux::CpuStats->new(initfile => '/tmp/cpustats.yml');
If you set "initfile" it's not necessary to call sleep before "get()".
It's also possible to set the path to the proc filesystem.
Sys::Statistics::Linux::CpuStats->new(
files => {
# This is the default
path => '/proc'
stat => 'stat',
}
);
init()
Call "init()" to initialize the statistics.
$lxs->init;
get()
Call "get()" to get the statistics. "get()" returns the statistics as a hash reference.
my $stats = $lxs->get;
raw()
Get raw values.
