How to collect CPU values from WMI. #perl #win32 #wmi

2011-03-10T05:23:00.000-08:00

This program will demonstrate how easy it is to obtain data from Windows Management Instrumentation (WMI), using a perl script. By analogy other information may be collected from WMI.

To obtain these data, I used the WMI Performance Counter class "Win32_PerfRawData_PerfOS_Processor" , which provides me the counters that measure aspects of processor(s) activity.

Since the data collected via WMI are percentages. I just needed to calculate the percentage of time used for each counter, depending on the time interval between measurements.



use strict;
use warnings;

use Win32::OLE;


my $interval = 1;
my $key = 'Name';
my @properties = qw(PercentIdleTime PercentProcessorTime PercentPrivilegedTime PercentUserTime PercentInterruptTime TimeStamp_Sys100NS);

my $hash1 = {};

my $wmi = Win32::OLE->GetObject("winmgmts://./root/cimv2")
 or die "Failed to get object\n";


my $list = $wmi->InstancesOf('Win32_PerfRawData_PerfOS_Processor')
 or die "Failed to get instance object\n";

my $v; 
foreach $v (in $list) {   
  map{$hash1->{$v->{$key}}->{$_}  = $v->{$_} }@properties;
}
 
while(sleep 1){

 $list = $wmi->InstancesOf('Win32_PerfRawData_PerfOS_Processor')
  or die "Failed to get instance object\n";
 
 my $hash = {};
 foreach $v (in $list) {   
  map{$hash->{$v->{$key}}->{$_}  = $v->{$_} }@properties;
 }

 my $cpu_time = sprintf("%.2f", (1 - get_value($hash1->{'_Total'}, $hash->{'_Total'}, 'PercentProcessorTime' )) * 100);
 my $cpu_idle = sprintf("%.2f", 100-$cpu_time);
 my $cpu_user = sprintf("%.2f", get_value($hash1->{'_Total'}, $hash->{'_Total'}, 'PercentUserTime' )* 100);
 my $cpu_priv = sprintf("%.2f", get_value($hash1->{'_Total'}, $hash->{'_Total'}, 'PercentPrivilegedTime' )* 100);
 my $cpu_int = sprintf("%.2f", get_value($hash1->{'_Total'}, $hash->{'_Total'}, 'PercentInterruptTime' )* 100);  
 printf "CPU Time %s %% , privileged %s %% , user %s %%, interrupt %s %%\n", $cpu_time,$cpu_priv,$cpu_user,$cpu_int;

 $hash1 = $hash;
}


exit;

sub get_value {
 my $h1 = shift;
 my $h2 = shift;
 my $property = shift;
 return (($h2->{$property} - $h1->{$property})/($h2->{'TimeStamp_Sys100NS'}-$h1->{'TimeStamp_Sys100NS'}));
}

Output sample:


CPU Time 2.03 % , privileged 1.96 % , user 0.00 %, interrupt 0.00 %
CPU Time 1.87 % , privileged 1.96 % , user 0.00 %, interrupt 0.00 %
CPU Time 2.16 % , privileged 1.96 % , user 0.00 %, interrupt 0.00 %
CPU Time 1.76 % , privileged 1.96 % , user 0.00 %, interrupt 0.00 %
CPU Time 2.19 % , privileged 1.96 % , user 0.00 %, interrupt 0.00 %
CPU Time 1.77 % , privileged 1.96 % , user 0.00 %, interrupt 0.00 %
CPU Time 1.98 % , privileged 1.96 % , user 0.00 %, interrupt 0.00 %
CPU Time 1.93 % , privileged 1.96 % , user 0.00 %, interrupt 0.00 %
CPU Time 2.08 % , privileged 1.96 % , user 0.00 %, interrupt 0.00 %
CPU Time 2.84 % , privileged 2.94 % , user 0.00 %, interrupt 0.00 %

Diff between two files (unordered and with different number of lines)

2010-09-08T10:23:00.000-07:00

This program will find the differences between two files, and should be applied in the following situations:

The files have different number of lines
The files are unordered.
`diff` fails to get the differences
Large files (the reason to use shell `sort` function)
Single record per line

For example: Imagine you have two files with a list of users, and these listings were taken from a database at different time instants. These listings will be different because users have been added and removed from the database. This script will help you to find the differences when `diff` can't resolve it.

#!/usr/bin/perl -w

use strict;

my $file1= $ARGV[0];
my $file2= $ARGV[1];

unless($file1 and $file2){
print "Usage: $0 <file1> <file2>\n\n";
exit;
}
unless( -f $file1){
print "File 1 does not exist: [$file1]\n\n";
exit;
}
unless( -f $file2){
print "File 2 does not exist: [$file2]\n\n";
exit;
}


my $tmp_file1 = '/tmp/f1.tmp';
my $tmp_file2 = '/tmp/f2.tmp';

`sort $file1 > $tmp_file1`;
`sort $file2 > $tmp_file2`;

open(F1, $tmp_file1) or die "$!";
open(F2, $tmp_file2) or die "$!";

my $read_f1 = 1;
my $read_f2 = 1;

my $s1;
my $s2;
while(1){

if (eof(F1)){print ">>$_" while <F2>;}
if(eof(F2)){print "<<$_" while <F1>;}

if($read_f1){$s1 = <F1>;}
if($read_f2){$s2 = <F2>;}

last unless $s1 and $s2;

$read_f1 = 1;
$read_f2 = 1;

next if ( lc($s1) eq lc($s2) );

if(lc($s1) gt lc($s2)){
print ">$s2";
$read_f1 = 0;
}else{
print "<$s1";
$read_f2 = 0;
}
}

unlink $tmp_file1 or die "$!";
unlink $tmp_file2 or die "$!";

How to kill TCP client connections

2010-05-12T09:46:00.000-07:00

Several times we are faced with a large number of TCP connections from the same source IP.
How to kill that connections?

This is an easy way:


$ for i in `lsof -i tcp@client_ip_address| awk '{print $2}'`; do kill -9 $i; done

Solaris: analyze a core dump file

2009-11-02T06:18:00.000-08:00

Whenever there is a coredump, the task of uncovering the source of the problem may not be easy. In Solaris we have some tools that will give us clues in order to solve the problem.

Coredump files on Solaris are generated in the directory:


/var/core/

Once in that directory, find your file core. Then run the following commands:


$ pstack

The command above shows the last state of the stack for each thread (lwp) of the program.
That isn't enough we need to know in each thread the problem have occurred. There is another command that lets us know that, the "pflags" command.


$ pflags 
core 'core_host_progname_1001_1_1256228346_13885' of 13885: /opt/coolstack/bin/perl -w /export/home/user/bin/progname
        data model = _ILP32  flags = MSACCT|MSFORK
 /1:    flags = STOPPED  yield()
        why = PR_SUSPENDED
        sigmask = 0xffbff8f7,0x0000fff7
 /2:    flags = STOPPED  lwp_park(0x0,0x0,0x0)
        why = PR_SUSPENDED
 /3:    flags = STOPPED
        why = PR_SUSPENDED
        lwppend = 0x00000400,0x00000000
 /4:    flags = 0
        sigmask = 0xffffbefc,0x0000ffff  cursig = SIGSEGV

Now we know know that thread 4 have received the SIGNAL "SIGSEGV" (Segmentation Fault).
So, the SIGSEGV was generated in Thread 4 when using a MySQL function "add_collation".

With that information isn't easy to know the reason of the coredump. Lets use another command, the "pmap".
The "pmap" command display information about the address space of a process, in this case the program that causes the coredump.


$ pmap | less

Since the problem occurred in the invocation of a MySQL function, with the "pmap" command, I've detected that my Perl used a DBD:: mysql library which was linked with a 32-bit MySQL library. My OS is 64 bits, however that is not a problem since 32 Bits libmysqlclient_32_bits is compatible with 64 bits MySQL DB's.
Despite all efforts to detect the problem in the program that I was developing, it was found that the problem was in the instance of a 64 bits MySQL DB that was using 32 bits libraries.

QMAIL + detect SMTP Attacks from the same IP

2009-10-29T08:43:00.000-07:00

A simple way to detect SMTP attacks from a single source IP can be achieved using the following command:


$ fgrep "tcpserver: pid"   "/var/log/qmail/smtp/current" | awk {'print $6'}| sort | uniq -c| sort  -rn |less

The output will be similar to:

How to recover a corrupted gzip file.

2009-09-21T03:59:00.000-07:00

Sometimes we are faced with a corrupted ".gz" file, with important information and we must recover it at any cost. Fortunately there is a tool able to recover these files in an efficient manner, the gzip Recovery Toolkit.

The installation process is very easy:

$ wget http://www.urbanophile.com/arenn/coding/gzrt/gzrt-0.5.tar.gz
$ tar -xzvf gzrt-0.5.tar.gz
$ cd gzrt-0.5
$ make

And that's it.

To start using it just do:

$ ./gzrecover file_to_recover.gz

then it will create a new filename called "file_to_recover.recovered"

You must also read the "Disclaimer and Warnings"

«This program is provided AS IS with absolutely NO WARRANTY. It is not guaranteed to recover anything from your file, nor is what it does recover guaranteed to be good data. The bigger your file, the more likely that something will be extracted from it. Also keep in mind that this program gets faked out and is likely to "recover" some bad data. Everything should be manually verified. »

 config.admin_get_author     = Proc.new { request.env['REMOTE_ADDR'] }
 config.after_setup          = Proc.new { true }


  # Includes AuthenticationSystem in the ComatoseAdminController
  #config.admin_includes << :authenticated_system

  # Calls :login_required as a before_filter

Java Tools - Finding bugs, optimization and profiling

2009-02-11T03:51:00.000-08:00

There a few tools for Java developers that can help us to be "better" programmers, (a bad programmer will allows be bad...). Finding bugs, optimization and profiling make part of a programmer day life, and why not using tools like these ones:

FindBugs

«FindBugs, a program wich uses static analysis to look for bugs in Java code»

http://findbugs.sourceforge.net/

«PMD scans Java source code and looks for potential problems like:

Possible bugs - empty try/catch/finally/switch statements
Dead code - unused local variables, parameters and private methods
Suboptimal code - wasteful String/StringBuffer usage
Overcomplicated expressions - unnecessary if statements, for loops that could be while loops
Duplicate code - copied/pasted code means copied/pasted bugs

PMD is integrated with JDeveloper, Eclipse, JEdit, JBuilder, BlueJ, CodeGuide, NetBeans/Sun Java Studio Enterprise/Creator, IntelliJ IDEA, TextPad, Maven, Ant, Gel, JCreator, and Emacs.»

http://pmd.sourceforge.net/

«YourKit, LLC is a technology leader, creator of the most innovative and intelligent tools for profiling Java & .NET applications. The YourKit Java Profiler has been already recognized by the IT professionals and analysts as the best profiling tool.

With YourKit solutions, both CPU and memory profiling have come to the highest professional level, where one can profile even huge applications with maximum productivity and zero overhead.

There are several, recent innovations to profiling that have gained well-deserved popularity among professional Java developers, both in big and small companies.

YourKit is the standard-setter in the evolution of profiling tools.»

Ajaxian » ECMA What? Harmony Who? TC39? Tamarin? JavaScript!

2009-02-04T14:52:00.000-08:00

There's a lot of misunderstanding among "javascript" and what it really means. I found an article that clarify it in a simply and direct way .

Ajaxian » ECMA What? Who? TC39? Tamarin? JavaScript!: "from the world."

I'm not a fan of ECMA and other standardization comities like , and the last issue about OOXML and ODF was a clear example, since they were very criticized and their decision was not well aceppted by all the user community.

Offline Gmail

2009-01-29T08:47:00.000-08:00

It starts to be a reality using the Gmail in off-line mode. Gmail uses Google Gears to store the relevant information synchronizing the information whenever we have an Internet connection. This allows us to do simple things such as reading the mail and sending emails. Of course, the effective sending of the mail will only be made from the moment we have a valid Internet connection. I can only say that this new feature will be very useful, the only penalty for now, is the fact that it is not available in Portugal. It's only available in the U.S. and UK.

Software Projects Cycle

2008-02-04T11:37:00.000-08:00

Software projects and all the processes involved are getting more and more predictable, I've found a picture (not new), that exposes all the cycle in a clear and simple way. Do you have a better way to described it?

Books & Newspapers of the future

Amazon.com: Kindle: Amazon's New Wireless Reading Device: Kindle Store

The world is changing very quickly and everyday something new appears. Today I found kindle a new approach in the way we read books and newspapers, it seems to me that it haves potential to be the substitute of books, magazines and newspapers.

gPhone its out there!!

2007-11-13T14:41:00.000-08:00

gPhone its out there but instead of a mobile phone , "gPhone" is a OS and development environment for developing mobile phone applications. Most of us were waiting for a mobile phone, however this new approach it's more interesting since there is a new competitor in the market that consequently will bring us more exciting "gPhones" with more open and widely spread mobile applications.

See this link for more information on "gPhone" or Android:

Forget iTunes

2007-10-31T21:25:00.000-07:00

For the music lovers Songbird it's an amazing desktop media player since it's mash up with the web and allows us to discover and organize local musics or even remote links/sites. It's only on a beta version but it promises to be the iTunes killer application. On this release I'm missing an export feature or even an distributed place to place my playlists and bookmarks.

Jabber Transports (or How to Connect Google Talk with Any IM)

2007-10-31T17:34:00.000-07:00

Google Talk allows us to connect to others IM networks, but with a drawback, Google Talk doesn't include a place to configure transports (i.e. the ability to provide a username and password for the IM network of choice). So one has to install another Jabber client in order to configure that transports.
After that you can use Google Talk to talk to all of your IM network friends.
