The Problem

Every organization has group of computers connected to a LAN and

there arises the problem to manage them properly

As the systems are used by different users in the organization there is

a possibility of misusing it.

The administrator has to monitor the systems regularly by going to

that point physically.

Also he has to do lot of work to know the details of softwares and

hardware on that particular system


3/51

Things done manually may lead to many problems

To Prevent the misuse of the systems

To reduce time taken to collect required information of remotesystem

Keeping several systems information records is difficult

Time-consuming process

Accessing, manipulating the data is difficult

Need for Automation


4/51

The details of the remote system are collected automatically

when ever they are requested

The data storage and access can be easy

The system provides a user friendly GUI

The remote system details can be viewed when the system is

turned off, if once they are collected

Proposed System


5/51

Processor: Pentium 2 or above

RAM: 256 MB

Hard disk: 20 GB

Technical Feasibility

Front End: Java

Back End: XML

6/51

The goal of the Project is to replace the traditional form of

maintenance and its accompanying inefficiencies with a moderninventory system.

The Administrator can get full control over the network

Implementation

Softwares Used:

o JAVA

o Network

o Servlet

o JSP

o XML

o Tomcat

o VB Script

The network is scanned only for the nodes that are requested for.

The collected information is stored in xml format. This is an universal format.


15/51

Code used forCollectingNode info.

VB Script: objWMIService = GetObject("winmgmts:\\" & strComputer &

"\root\cimv2")

colItems = objWMIService.ExecQuery("Select * from

Win32_ComputerSystem",,48)

JAVA Code: Runtime x=Runtime.getRuntime();

p=x.exec("cscript C:\\WINDOWS\\system32\\sys.vbs");


16/51

Testing

Validations

The No. of Nodes for scanning field must contain integer value

The Node name must start with alphabet

The IP Address entered must be the standard format (Ex. 120.0.0.13)

The range specified for IP scan must be a valid one.

ScopeOf The System

The Network Inventory system is used to collect the inventory

information of systems present in LAN.

The System can be further developed to display the processes running in

remote system and also to terminate them.

The CPU performance graph of the specified system can also be

displayed

Conclusion

It is easy to use, since it uses the GUI provided in the user dialog.

User-friendly screens are provided.

The usage of software increases the efficiency, decreases the effort.

It has been thoroughly tested and implemented.

It has also helped overcome the drawbacks of the existing system.

Limitations: This project is mainly concentrated on the LAN of aparticular organization.
