How to bypass windows vista login screen PDF Print E-mail
Written by Administrator   
Thursday, 10 July 2008

In most of the cases you would want to set password for your login since you access the services from remote. but you want your vista to log you in without asking password. to make that work:

Start sphere, then enter "cmd" in the search box. In the Command Prompt window write "control userpasswords2" and hit enter.

Windows Vista will now ask you to elevate the privileges of the process so do it and you will be face to face with a window for User Accounts. Toward the top you will be able to see the option "users must enter a user name and password to use this computer." Select the account you wish to alter and then uncheck the option. You will then be prompted with an Automatically Log On window, in which you will have to enter your name and password.

ZABBIX The Ultimate Monitoring Solution PDF Print E-mail
Written by Administrator   
Wednesday, 05 March 2008
 Doc source http://www.zabbix.com

What is ZABBIX?

ZABBIX is an enterprise-class open source distributed monitoring solution.

ZABBIX is software that monitors numerous parameters of a network and the

health and integrity of servers. ZABBIX uses a flexible notification mechanism

that allows users to configure e-mail based alerts for virtually any event. This

allows a fast reaction to server problems. ZABBIX offers excellent reporting and

data visualisation features based on the stored data. This makes ZABBIX ideal

for capacity planning.

ZABBIX supports both polling and trapping. All ZABBIX reports and statistics, as

well as configuration parameters are accessed through a web-based front end.

A web-based front end ensures that the status of your network and the health of

your servers can be assessed from any location. Properly configured, ZABBIX

can play an important role in monitoring IT infrastructure. This is equally true for

small organisations with a few servers and for large companies with a multitude

of servers.

ZABBIX is free of cost. ZABBIX is written and distributed under the GPL General

Public License version 2. It means that its source code is freely distributed and

available for the general public. Both free and commercial support is available

and provided by ZABBIX Company.

 

ZABBIX offers:

auto-discovery of servers and network devices

distributed monitoring with centralised WEB administration

support for both polling and trapping mechanisms

server software for Linux, Solaris, HP-UX, AIX, Free BSD, Open BSD, OS X

native high performance agents (client software for Linux ,Solaris, HP-UX, AIX,

Free BSD, Open BSD, OS X, Tru64/OSF1, Windows NT4.0, Windows 2000,

Windows 2003, Windows XP, Windows Vista)

Use of ZABBIX

 

Distributed monitoring

Auto-discovery

Pro-active monitoring

Monitoring of WEB applications

ZABBIX provides very efficient scenarios-based way of monitoring WEB

applications. Both HTTP and HTTPS are supported.

Performance monitoring

One of most important uses of ZABBIX is performance monitoring. Processor

load, number of running processes, number of processes, disk activity, status of

swap space, and memory availability are some of the numerous system

parameters ZABBIX is able to monitor.

ZABBIX provides a system administrator with timely information about

performance of a server. In addition, ZABBIX can produce trend graphs to help

identify bottlenecks in system performance.

Alerting users

Having performance monitoring is good, but it is almost useless without a

powerful notification mechanism. With ZABBIX, an administrator can define

virtually any possible condition for a trigger, using flexible expressions. Any time

these expressions become true (or false), an alert will be emailed to any address

defined by the administrator.

External programs can be used for user-defined notification methods such as

SMS, phone notifications, etc.

ZABBIX can predict future behavior of monitored parameters using Least

Square Algorithm. This allows user to be notified even before system state

achieves critical level. Note: This functionality will be completed in future

versions of ZABBIX

 

Monitoring of log files

ZABBIX can be used for centralized monitoring of log files. Note: This

functionality will be completed in future versions of ZABBIX

Integrity Checking

ZABBIX is capable of server integrity monitoring. All critical configuration files,

binaries, kernel, scripts, and web server HTML pages can be monitored by

ZABBIX so that the administrator can be alerted to modifications made to these

files.

Logging services

All values of monitored parameters are stored in a database. The collected data

can be used later for any purposes.

Capacity planning

Viewing trends of process load, disk usage, database activity, or other important

metrics allows a system administrator to clearly see when the next hardware

upgrade should be made.

Assuring and monitoring of SLA

ZABBIX is able to monitor Service Level Agreements (SLA). It also keeps SLArelated

historical data that helps to identify and improve weak areas of an IT

infrastructure.

High level view of IT resources and services

A High level service tree allows the creation of dependencies between various IT

resources. Such representation enables the following questions to be answered:

What IT services depends on availability of resource X?

Example: If processor load is too high on server A, then these IT services will be

affected: Oracle server, WEB banking, online transaction processing, etc.

What resources specific IT service depends on?

Example: WEB portal may depend on the following resources:

processor load on server A

connection to ISP provider

disk space on volume /data on server A

availability of Oracle DB engine on server B

speed of execution of user requests

availability of Apache server on server etc etc

Such a dependency tree helps identify weak points in IT infrastructure.

Example: If several critical services offered by IT department depends on, for

example, availability of disk space on some server, then it is time to think about

distribution of the volume across different servers or disk arrays to eliminate

possible risks.

 

Other

 

availability analysis

graphical representation of collected information

Network maps

custom screens
