Overview of this book

This book is a perfect starting point for monitoring with Zabbix. Even if you have never used a monitoring solution before, this book will get you up and running quickly, before guiding you into more sophisticated operations with ease. You'll soon feel in complete control of your network, ready to meet any challenges you might face. Beginning with installation, you'll learn the basics of data collection before diving deeper to get to grips with native Zabbix agents and SNMP devices. You will also explore Zabbix's integrated functionality for monitoring Java application servers and VMware. Beyond this, Zabbix Network Monitoring also covers notifications, permission management, system maintenance, and troubleshooting - so you can be confident that every potential challenge and task is under your control. If you're working with larger environments, you'll also be able to find out more about distributed data collection using Zabbix proxies. Once you're confident and ready to put these concepts into practice, you'll find out how to optimize and improve performance. Troubleshooting network issues is vital for anyone working with Zabbix, so the book is also on hand to help you work through any technical snags and glitches you might face. Network monitoring doesn't have to be a chore - learn the tricks of the Zabbix trade and make sure you're network is performing for everyone who depends upon it.

Proxies and availability monitoring


With all the benefits that a proxy brings, one would be tempted to use them a lot—and a good idea that would be, too. Proxies are really great. There's still the issue of monitoring availability for hosts behind proxies. If a proxy goes down or cannot communicate with the Zabbix server, we would be missing data for all the hosts behind that proxy. If we used the nodata() trigger function to detect unavailable hosts (we could call such triggers availability triggers), that could mean thousands of hosts declared unavailable. Not a desirable situation. There is no built-in dependency for hosts behind a proxy, but we can monitor proxy availability and set trigger dependencies for all hosts behind that proxy. But what should we set those dependencies to? Let's discuss the available ways to monitor proxy availability and their potential shortcomings.
