Nagios Building Enterprise-Grade Monitoring Infrastructures for Systems and Networks

This is the definitive guide to building cost-effective, enterprise-strength monitoring infrastructures with the latest commercial and open source versions of Nagios, the world's leading monitoring toolset. World-renowned network monitoring expert David Josephsen covers the entire monitoring software stack, from SNMP to advanced visualization, treating Nagios as a specification language and foundation for building well-designed monitoring systems that can scale to serve the needs of any organization. Drawing on his unsurpassed enterprise monitoring experience, Josephsen demonstrates best practices throughout, and also reveals common mistakes, their consequences, and how to avoid them. He provides all the technical depth you need to implement and run Nagios successfully, including detailed coverage of creating agents programmatically in Windows and Unix, and an extensive discussion of using the C-based Nagios Event-Broker API: information available in no other book. Easy-to-adapt code listings accompany many topics. Coverage includes: * Nagios setup and configuration, including important new configuration parameters * New plug-ins, including check-MK, Op5 plug-ins for Windows and Unix, SFlow, and more * Scaling and performance optimization in large enterprise installs * Choosing the best new options for visualizing data (including Ganglia and Graphite) * Reviewing use cases so you can identify the applications that offer you the most value

David Josephsen is the Director of Systems Engineering at DBG, Inc., where he maintains a gaggle 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. He authored the book "Building a Monitoring Infrastructure with Nagios" (Addison Wesley), is a contributor to the O’Rielly book on Ganglia, and currently writes "iVoyer", the systems monitoring column for ;login magazine.
