Performance Monitoring - RHEL 7.4
Have a question about doing some performance monitoring - how to approach it.
This is on RHEL 7.4
We are moving a rather large application to new hardware in the future. I would like to find a way to compared performance on the new hardware at different stages and at different times.
I'm familiar with the basic tools, such as top - and I've found an app called 'stress' that can be used to put various loads on the system.
But I am wanting to make a comparison on how the performance varies or does not vary after things like: Firmware upgrades, App installs, etc.
Any suggestions on a method/process or tool maybe that can assist with this? I can cap out the loads with 'stress' but I'm not sure what that will tell me. My first thought was to run the app with a certain set of parameters and then compare future runs using the same set of parameters. I would need or like it to be able to log results at set intervals via cron or something similar.
But looking for suggestions
Thanks!

hi,
can any one tell me, is there is any way i can check the performance of my solaris 8 os on an Ent 3500. Other than top to check for the top most processes, how to make the calculations with vmstat, iostat, mpstat and nfsstat. Or is there any other tools that i can use?
cheers. (3 Replies)

Hi All
I am looking for a script that would collect statistics in a summarised format.
CPU, Memory,Swap, Wait queue, Run queue and disk activity.
Something that would allow me to profile the environment based on a 1 line output that I could run every 15 min.
Thx

sdl::app
SDL::App(3) User Contributed Perl Documentation SDL::App(3)
NAME
SDL::App - a SDL perl extension
SYNOPSIS
use SDL;
use SDL::Event;
use SDL::App;
my $app = new SDL::App (
-title => 'Application Title',
-width => 640,
-height => 480,
-depth => 32 );
This is the manual way of doing things
my $event = new SDL::Event; # create a new event
$event->pump();
$event->poll();
while ($event->wait()) {
my $type = $event->type(); # get event type
print $type;
exit if $type == SDL_QUIT;
}
An alternative to the manual Event processing is the L<SDL::App::loop> .
DESCRIPTION
SDL::App controls the root window of the of your SDL based application. It extends the SDL::Surface class, and provides an interface to
the window manager oriented functions.
METHODS
new
"SDL::App::new" initializes the SDL, creates a new screen, and initializes some of the window manager properties. "SDL::App::new" takes a
series of named parameters:
o -title
o -icon_title
o -icon
o -width
o -height
o -depth
o -flags
o -resizeable
title
"SDL::App::title" takes 0, 1, or 2 arguments. It returns the current application window title. If one parameter is passed, both the
window title and icon title will be set to its value. If two parameters are passed the window title will be set to the first, and the icon
title to the second.
delay
"SDL::App::delay" takes 1 argument, and will sleep the application for that many ms.
ticks
"SDL::App::ticks" returns the number of ms since the application began.
error
"SDL::App::error" returns the last error message set by the SDL.
resize
"SDL::App::resize" takes a new height and width of the application if the application was originally created with the -resizable option.
fullscreen
"SDL::App::fullscreen" toggles the application in and out of fullscreen mode.
iconify
"SDL::App::iconify" iconifies the applicaiton window.
grab_input
"SDL::App::grab_input" can be used to change the input focus behavior of the application. It takes one argument, which should be one of
the following:
o SDL_GRAB_QUERY
o SDL_GRAB_ON
o SDL_GRAB_OFF
loop
"SDL::App::loop" is a simple event loop method which takes a reference to a hash of event handler subroutines. The keys of the hash must
be SDL event types such as SDL_QUIT(), SDL_KEYDOWN(), and the like. The event method recieves as its parameter the event object used in
the loop.
Example:
my $app = new SDL::App -title => "test.app",
-width => 800,
-height => 600,
-depth => 32;
my %actions = (
SDL_QUIT() => sub { exit(0); },
SDL_KEYDOWN() => sub { print "Key Pressed" },
);
$app->loop(\%actions);
sync
"SDL::App::sync" encapsulates the various methods of syncronizing the screen with the current video buffer. "SDL::App::sync" will do a
fullscreen update, using the double buffer or OpenGL buffer if applicable. This is prefered to calling flip on the application window.
attribute ( attr, [value] )
"SDL::App::attribute" allows one to set and get GL attributes. By passing a value in addition to the attribute selector, the value will be
set. "SDL:::App::attribute" always returns the current value of the given attribute, or croaks on failure.
