Build real-world, end-to-end network monitoring solutions with Nagios This is the definitive guide to building low-cost, enterprise-strength monitoring infrastructures with Nagios, the world’s leading open source monitoring tool. Network monitoring specialist David Josephsen goes far beyond the basics, demonstrating how to use third-party tools and plug-ins to solve the specific problems in your unique environment. Josephsen introduces Nagios “from the ground up,” showing how to plan for success and leverage today’s most valuable monitoring best practices. Then, using practical examples, real directives, and working code, Josephsen presents detailed monitoring solutions for Windows, Unix, Linux, network equipment, and other platforms and devices. You’ll find thorough discussions of advanced topics, including the use of data visualization to solve complex monitoring problems. This is also the first Nagios book with comprehensive coverage of using Nagios Event Broker to transform and extend Nagios. Understand how Nagios works, in depth: the host and service paradigm, plug-ins, scheduling, and notification Configure Nagios successfully: config files, templates, timeperiods, contacts, hosts, services, escalations, dependencies, and more Streamline deployment with scripting templates, automated discovery, and Nagios GUI tools Use plug-ins and tools to systematically monitor the devices and platforms you need to monitor, the way you need to monitor them Establish front-ends, visual dashboards, and management interfaces with MRTG and RRDTool Build new C-based Nagios Event Broker (NEB) modules, one step at a time Contains easy-to-understand code listings in Unix shell, C, and Perl If you’re responsible for systems monitoring infrastructure in any organization, large or small, this book will help you achieve the results you want–right from the start. David Josephsen is Senior Systems Engineer at DBG, Inc., where he maintains a collection of geographically dispersed server farms. He has more than a decade of hands-on experience with Unix systems, routers, firewalls, and load balancers in support of complex, high-volume networks. Josephsen’s certifications include CISSP, CCNA, CCDA, and MCSE. His co-authored work on Bayesian spam filtering earned a Best Paper award at USENIX LISA 2004. He has been published in both ;login and Sysadmin magazines on topics relating to security, systems monitoring, and spam mitigation.

How Optimizing SQL Servers Can Reduce The Need For Scaling
There comes a time in every database production environment when you must decide whether or not to scale hardware systems. There are variables such as time frames and budgets that make this decision very difficult. A very significant decision is choosing to scale up or scale out.
Scaling up means to move databases and applications to a larger class of hardware with more powerful processors, more memory, and faster disk drives. Using higher levels of system resource could require you to scale up the production environment to be certain that end users are receiving the best experience.

Scaling out means to implement the use of federated servers where data is partitioned or replicated across them. For instance, you could partition CRM or ERP functionality on separate servers and partition horizontal data across various databases.
Consider SQL Server Performance Tuning
Before scaling up or out, you must be sure that it is required. Performing the proper SQL server performance tuning can aid you in making that decision. Most performance and scalability issues can be resolved through SQL server optimization. The decision to scale up or scale out should be set aside until SQL server databases and applications are optimized by analyzing past trends and wait time performance information.
A majority of performance bottlenecks such as inefficient locking, bad indexes, and unprepared SQL statements that cause overloaded CPUs, and disk input/output utilization can be resolved with SQL server optimization instead of scaled up hardware.
Should You Scale Up Or Scale Out?
After you have done the proper SQL server optimization, and still are having performance problems, the next decision must be to scale up or scale out. The first solution is to scale up. Although it can be costly to scale up, it is certainly simpler and more efficient than scaling out. Scaling up includes replacing slow hardware components with newer, faster ones and/or adding more hardware to existing configurations.
If, once you have scaled up on hardware, your system is still experiencing performance issues, you should consider scaling out and implementing a federated server environment. The decreased load on individual servers should alleviate most remaining performance issues.
If you don't have the funding to purchase new hardware (scale up), scaling out becomes a viable option. If you currently have sufficient, or almost sufficient server capacity, you have the opportunity to significantly diminish expenditures. You must, however, determine whether the cost savings is worth the added complexity of running a federated server environment.
Discover more benefits of SQL Server Optimization.
Optimize First, Scale Later
It bears repeating that the most and least expensive performance enhancing optimization occurs at the application and database levels. Concentrating server performance tuning in those areas will commonly phase out the need for scaling. Make sure that you have tried every performance optimization option before you decide that scaling is the only way to solve your performance issues.
