This is how you can identify memory growth per process
The file mem1 contains the pid and rss and vsz values.
After a couple of minutes do it again but this time to file mem2
Now you can compare mem1 and mem2.
A helpful command is

Hi all,
I tried to output memory usage information while the process is
executing at a particular time. I found out some people
suggesting calling the ioctl. I followed it and wrote a test example:

#include <stdlib.h>
#include <iostream.h>
#include <fcntl.h>

Hi Guys,
I work on a AIX environment and I'm trying to write a script where I can collect all the memory used by a process. Basically I'm executing the command 'ps -fu userid' to get all the process ids and then executing the 'ps v PID' to get all the memory allocated by PPID. My question is... (2 Replies)

I am currently having trouble to get nmon to print me the actual CPU usage for an interval for a process.

hi all gurus:
I want to find out Solaris process memory usage, but got a bit confused, see if any one can provide me some guidance.

io::async::pid
IO::Async::PID(3pm) User Contributed Perl Documentation IO::Async::PID(3pm)NAME
"IO::Async::PID" - event callback on exit of a child process
SYNOPSIS
use IO::Async::PID;
use POSIX qw( WEXITSTATUS );
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $kid = $loop->fork(
code => sub {
print "Child sleeping..
";
sleep 10;
print "Child exiting
";
return 20;
},
);
print "Child process $kid started
";
my $pid = IO::Async::PID->new(
pid => $kid,
on_exit => sub {
my ( $self, $exitcode ) = @_;
printf "Child process %d exited with status %d
",
$self->pid, WEXITSTATUS($exitcode);
},
);
$loop->add( $pid );
$loop->run;
DESCRIPTION
This subclass of IO::Async::Notifier invokes its callback when a process exits.
For most use cases, a IO::Async::Process object provides more control of setting up the process, connecting filehandles to it, sending data
to and receiving data from it.
EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_exit $exitcode
Invoked when the watched process exits.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
pid => INT
The process ID to watch. Must be given before the object has been added to the containing "IO::Async::Loop" object.
on_exit => CODE
CODE reference for the "on_exit" event.
Once the "on_exit" continuation has been invoked, the "IO::Async::PID" object is removed from the containing "IO::Async::Loop" object.
METHODS
$process_id = $pid->pid
Returns the underlying process ID
$pid->kill( $signal )
Sends a signal to the process
