How to Analyze Remote IIS 7 Log using Indihiang 0.2

Agus Kurniawan — Wed, 01 Jul 2009 04:24:27 GMT

When you use Indihiang 0.2 to analyze IIS log via IIS Remote on IIS7 on Windows Server 2008, sometimes you get error although you have filled administrator level. This problem occurs because Indihiang 0.2 uses WMI to get all log files on remote IIS so IIS7 should be configured for WMI compatibility using adding features on Server Management as below

Indihiang 0.2 Inside :: Support Parallel Tasks and Processes

Agus Kurniawan — Mon, 08 Jun 2009 17:00:15 GMT

To increase scalability Indihiang 0.2 provides features to enable web log analyzing with multi processes. Each process can do parallel tasks.

Technical Design

Once you open file, multi files, or remote IIS Indihiang 0.2 will create an Indihiang Log Parser for you. This means one analyzing process has one an Indihiang Log Parser so if an Indihiang Log Parser get problems (it may corrupt log files) then this will not impact for another Indihiang Log Parser.

Each Indihiang Log Parser will create parallel tasks if there are multi log files to be analyzed. I use Microsoft Parallel Extensions to .NET Framework 3.5 technology to implement parallel computing. Due to implementing parallel tasks so you will not get sequential process on status

Multiple Process with Parallel Tasks

Indihiang 0.2 enables you to open log file again without waiting finishing previous process. This means Indihiang 0.2 can work multiple process. Each process will do parallel tasks to analyze

Analyzing Indicators

Indihiang 0.2 provides indicators you can monitoring the process is working or not. There are two Indicators. The first indicator is a progress bar as below

The second indicator is status. Every activity will log on this status window.

IIS Log File Consolidation Feature will be Released on Indihing 0.2

Agus Kurniawan — Wed, 06 May 2009 05:21:39 GMT

Finally I finished the IIS log file consolidation for Indihiang tool two weeks ago. With this feature, you can analyze multiple IIS log files. I have tested with 276 IIS log files (thanks for Erudeye Enterprise team for providing test data). It spent less than 20 seconds on Intel Core Duo 1.8 GHz on Windows Vista 32-bit. Remember it still used the sequential processing!!. It’s fast because I changed data structure to store IIS log file object on the previous Indihiang version. I utilize generic dictionary collection with custom binary tree data structure. Currently I’m implementing Indihiang tool using parallel processing approach using Microsoft Parallel Extensions to .NET Framework 3.5 so I must change processing algorithms. I would like to utilize fully all processor cores to compute IIS log analyzing.

Here are figures of the sample of Indihiang tool analyzing result.

You will get this feature on Indihiang tool on the next release, Indihiang 0.2. I’ll announce when Indihiang 0.2 will be released.

Indihiang Project Roadmap for Indihiang 0.2

Agus Kurniawan — Wed, 06 May 2009 04:51:01 GMT

Since first released on 15 April 2009, total download of Indihiang tool is 559 (today) [V]. I would like to thank to all you for supports. I also got feedbacks via email about requested features. Please contact me if you any idea or new feature for this project.

Today I would like to share the Indihiang roadmap for the next version , Indihiang 0.2. Here is the highlight feature for Indihiang 0.2

IIS Log File Consolidation

Fortunately, IIS log file consolidation can be released on Indihiang 0.2. I know one of you sent emails about multiple IIS log files analyzing. Yeah, on the original roadmap this feature should be release on Indihiang 0.1 but I postponed so I confirm this feature will be released on the next version of Indihiang tool (version 0.2).

Bandwidth Analyzing

I got feedbacks from Indihiang users that want to analyze bandwidth usage on web server based on IIS log file. On the next release, I put this feature to be released on version 0.2. With the feature you can see bandwidth usage such as bandwidth In/Out. This tool also analyze the bandwidth usage relate to IP Address client so we can know how many bandwidth IP Address client utilize on web server.

Updated Hits Analyzing by Month and Year

On current released version, you can only see the Hits analyzing by day so the next version Indihiang tool will implement Hits analyzing by day, month and year.

Parallel Processing

To improve the performance of Indihiang tool I’ll implement parallel processing approach. This means Indihiang tool will utilize all processor cores to compute analyzing. Parallel processing technology that I’ll implemet on Indihiang tool is Microsoft Parallel Extensions to .NET Framework 3.5.

Any Feedback?

If you have idea(s) to improve Indihiang tool and to enrich Indihiang tool features, please let me know..

Release Indihiang Tool for x64 Platform

Agus Kurniawan — Sat, 18 Apr 2009 15:23:49 GMT

After released version 0.1, I got feedbacks about Indihiang tool for x64 environment. Actually Indihiang tool can run on x64 environment. You just copy all Indihiang files into x64 machine or you install a setup file of Indihiang tool. This can run because it utilizes WOW64 feature. WOW64 is a compatibility environment provided by the operating system that allows a 32-bit application to run on a Windows 64-bit operating system. It works but this tool can’t utilize x64 advantages so I want to port and build for x64 machine.

Porting to .NET Framework 3.5 for 64-Bit.

.NET Framework supports for 64-bit started from version 2.0. Microsoft also provides Visual Studio 2005/2008 tool that we can compile .NET app on specific platform through configuration manager.

Indihiang tool code was written in pure managed code so it’s not difficult to migrate into 64-bit platform. I tested the binary file of Indihiang tool and run well. After that, I packaged Indihiang tool into a setup project in Visual Studio 2008. All packaging was success and then I copied into x64 machine ( I used a x64 machine with Windows Server 2008 R2 x64), uppsss… I got an error message while installing as below

This error is due to my custom action (x64 platform target) in setup project still has dependency from 32-bit MSI library. As we know, MSI can run on 32-bit and 64-bit. To solve this, I must force MSI to run 64-bit .NET library to execute my custom action. The best way is to change MSI configuration using ORCA. After I changed MSI configuration I run my MSI on 64-bit platform.

Now, you can download the setup file of Indihiang tool for x64 platform on http://www.codeplex.com/indihiang

Indihiang Tool for Itanium Platform

Next week I want to compile and test Indihiang tool for Itanium platform. If you have a machine based on Itanium platform you can participate for this testing. Please contact me if want to be tester.

Tampilan ASP.NET jadi Ladyboy ketika Dibuka dengan IE8

Agus Kurniawan — Sun, 05 Apr 2009 09:06:01 GMT

Minggu lalu gw install IE8 pada notebook Windows Vista 32-bit. Secara fitur memang banyak sekali ditawarkan oleh IE8. Ada bisa melihat para developer blogger memberikan informasi kelebihan dari IE8.

Terlepas pro dan kontro terhadap IE8. Gw sendiri setelah install ada beberapa anomali seperti ketika kita masuk website yang ada flash kadang kalanya IE8 mengalami hang walaupun flash gw sudah di upgrade ke flash 10. kalau anda pakai flash 9 lebih parah hang ketikan memakai browser IE8.

Aplikasi ASP.NET

Setelah gw upgrade browser IE8, gw melanjutkan untuk coding ASP.NET. Gw perhatikan seperti ada anomali yaitu tampilan berubah. Gw oprek sana-sini rupanya tidak berubah sama sekali…oh.shiit..ini apa sih. Gw coba jalanin Virtual OS gw dengan Windows Vista tetapi IE7 dengan gw browse lagi aplikasi ASP.NET, well bagus dan tidak berubah. Haaah, ini kambing merah ada di IE8.

Gw coba google dan masuk diskusi baik eksternal dan internal mengenai IE8, rupanya memang banyak sekali cerita dibalik IE8. So bagi anda yang sudah membangun aplikasi ASP.NET dengan memanfaatkan CSS, menangis anda karena tampilan ASP.NET akan berubah ketika dilihat dengan browser IE8

Solusi tercepat supaya tampilan aplikasi ASP.NET normal pada IE8 maka setiap page dipasang script diantara tag <HEAD> </HEAD>:

        1: <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
  

kalau page banyak banget dan gak paka masterpage yang sial anda tapi kalau pakai masterpage maka cukup menambahhkan di masterpage saja.

Solusi panjang maka aplikasi mesti revisi CSS sesuai dengan kebaruan pada IE8, cek di URL ini

http://msdn.microsoft.com/en-us/library/cc288472.aspx

Alternatif anda bisa menggunakan CSS Adapter, itu info dari komunitas tapi tetap aja masih problem ketika browse melalui IE8

Bukuku "Supervised Neural Networks"

Agus Kurniawan — Tue, 17 Mar 2009 04:51:37 GMT

Buku Supervised Neural Networks yang diterbitkan oleh Graha Ilmu tahun 2006 merupakan buku pertama gw untuk bidang science. Buku ini ditulis bersama dengan Prof.Dr.Ir. Mauridhi Hery Purnomo, M.Eng (guru besar intelligent system dari T. Elektro ITS). gw sendiri membantu dalam implementasinya. Ide penulisan ini diawali ketika gw menyelesaikan s1 T. Elektro ITS. Habis lulus gw langsung kerja di Balicamp as Software Engineer. Di Balicamp gw masih ber-email ria dengan Prof. Hery selesai juga (cukup lama hampir 4 tahun-an) lantaran kesibukan beliau. Berbarengan dengan itu gw juga menulis buku-buku seputar programming dan IT professional. Cek disini [V]. Akhirnya buku ini selesai dan terbit di tahun 2006.

Abstrak Buku

Buku ini membahas teknologi jaringan saraf tiruan (neural networks) jenis pelatihan terbimbing (supervised learning) secara rinci, mudah dipahami dan dasar teori yang umum digunakan serta beberapa contoh aplikasinya. Tujuannya adalah menambah pengkayaan pustaka nasional di bidang ilmu kecerdasan buatan yang semakin hari semakin banyak dibutuhkan karena semakin luas aplikasinya. Sebagai bagian dari teknologi kecerdasan buatan, jaringan saraf tiruan utamanya jenis pelatihan terbimbing semakin banyak terlibat sebagai tool yang handal untuk berbagai disiplin ilmu seperti kedokteran, teknik, ekonomi, manajemen dan bahkan disiplin ilmu sosial yang biasanya menggunakan statistik sebagai alat komputasinya. Sehingga teknologi komputasi cerdas ini dirasakan semakin diperlukan kehadirannya.

Selengkapnya akan dibahas hal-hal sebagai berikut

Struktur Dasar JST Pelatihan Terbimbing dan Pemodelannya
Metoda Pelatihan Terbimbing dan Modifikasinya
Metoda Pemrograman JST Pelatihan Backpropagation
Aplikasi Teknologi Supervised Neural Network

Software Aplikasi

Buku ini implementasi menggunakan Delphi, dulu yang digunakan versi 3.0. Sekarang Delphi sudah versi Delphi 2009. Oleh karena itu gw untuk upgrade code nya dan share source code buku ini. Algoritma Neural Network Back propagation ini gw gunakan juga dalam tugas akhir saya dengan nama project Visual Speech (lihat gambar dibawah) namun bedanya gw konversi kedalam C++.

Upgrade Software Pada Buku

Karena ada banyak email masuk yang mengenai ini, gw coba meng-upgrade software buku ini sehingga pembaca menggunakan dengan versi Delphi yang baru. Well, gw juga konversi ke C# bagi pembaca yang menggunakan Visual Studio 2008. Informasi selengkapnya perkembangannya dapat di blog pribadi gw di http://blog.aguskurniawan.net karena blog yang disini gw peruntukan untuk mengenai topik teknologi Microsoft. kalau ingin memperoleh notifikasi source code yang telah diupgrade, rekan-rekan dapat mengirim email ke gw yaitu agusk2007 [at] gmail.com Nanti gw email kalau sudah di upgrade source code ini.
