Nagios 3 Enterprise Network Monitoring: Including Plug-Ins and Hardware Devices
Author: Max Schubert
Nagios is an Open Source network, hardware, and application monitoring program. It is designed to inform system administrators of problems on their networks before their clients, end-users or managers do. Nagios is a SysAdmin's best friend. Nagios is installed on over 300,000 machines worldwide, and truly is a global product: approximately 25.6% of users are in the U.S., and 30% in EMEA. Nagios can monitor everything from network bandwidth to the temperature and humidity in a server room. SysAdmins are able to use Nagios for such a variety of purposes through custom software "plug ins" and third party hardware. SysAdmins customize these plug ins instructing Nagios to monitor the servers, applications, or devices that are most critical to their network infrastructure. These plug ins also allow SysAdmins to integrate Nagios with other monitoring devices and applications like Snort and Wireshark. Nagios can also be fully integrated with third party environmental monitoring devices and remote power supplies. When Nagios detects a problem, it can notify the SysAdmin in a variety of different ways (email, instant message, SMS, etc.). Current status information, historical logs, and reports can all be accessed via a web browser. Nagios could send a text message to a SysAdmin sitting on his couch at home that the temperature in the server room is too hot and could potentially damage the equipment. The SysAdmin can then check the status of the server from home using his Nagios Web interface, and then coordinate with the appropriate facility management personnel to check the air conditioning in the server room. This is merely one example of Nagios? capabilities. The same scenario couldbe applied to an overloaded Exchange server, a router being pounded by a Denial of Service Attack, or a user accessing or downloading unauthorized materials.

An Intermediate Guide to SPSS Programming: Using Syntax for Data Management
Author: Sarah Boslaugh
"The book makes a distinct and important contribution to the field by focusing on an important set of skills that is often only briefly touched upon (if at all) in courses or texts. SPSS users benefit from having solid familiarity with syntax coding in addition to being able to use the pull-down menus. A careful study of this book will help readers advance these important skills."
--Eric Einspruch, RMC Research Corporation
"Where was this manual when I was trying to learn SPSS for my dissertation after switching from MiniTab? It would have been a valuable tool to save enormous amounts of time. It is succinct and to the point."
--Wanda J. Long, St. Charles Community College
An Intermediate Guide to SPSS Programming: Using Syntax for Data Management introduces the major tasks of data management and presents solutions using SPSS syntax. This book fills an important gap in the education of many students and researchers, whose coursework has left them unprepared for the data management issues that confront them when they begin to do independent research. It also serves as an introduction to SPSS programming. All the basic features of SPSS syntax are illustrated, as are many intermediate and advanced topics such as using vectors and loops, reading complex data files, and using the SPSS macro language.
Key Features
• Overview of data management issues, with practical solutions
• A beginner-level introduction to SPSS and computer programming
• Many examples of SPSS syntax and annotated output
• Chapters on date and time variables in SPSS, missingdata, nonstandard data files, and SPSS macro language, and random processes
An Intermediate Guide to SPSS Programming will be a welcome addition to advanced undergraduate and graduate statistics courses across the social sciences, education, and health. Professional researchers, data managers, and statisticians will also find this an invaluable reference for SPSS and data management.
