Please let me know what are all the reasons in increase in the Memory utilisation of ux servers, and the solutions to face those issues caused by the memory utilisation (memeory Likage)?
Thanks in Advance!

Hi all,
This is my first post, so at the beginning I would like to be nice and say: "Hello all!" :)
I am looking for a C/C++ library for Linux CPU statistics. All I found is that it is possible to parse two files: /proc/cpuinfo and /proc/stat to gain some needed information, but I would like to... (1 Reply)
Hi All,
Does anyone know what the best commands in the UNIX command line are for obtaining this info:
current CPU usage
memory usage
virtual memory usage
preferably with date and time parameters too?
thanks

Hi,
We have an issue on our lpar where the pin memory usage slowly and regularly increases approx 1.5% a day until it reaches its 80% threshold
We have to regularly reboot the lpars to release the pin memory as we have found that killing all processes does not release it.
However,... (1 Reply)

Hello,
Looking for some help. I am trying to gather data at each server showing when the physical CPU is being used the most based on a weekly timeframe.
I know this data can be seen through NMON but with multiple servers in our environment it could take a real long time. is there a easier... (4 Replies)
Hi,
We have around 1000 server (Red Hat + Suse + Parallels + Solaris-9/10/11). Every month, we generate a report for all servers for CPU and Memory utilization in 'percentage used'. This report is generated from HP Openview and frequency is every file minutes. In HP OpenView, we are picking 20... (0 Replies)
I am facing issue related to performance of one customized application running on RHEL 5.9. The application stalls for some unknown reason that I need to track.

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.
