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.

Performance considerations


Zabbix tends to perform nicely for small installations, but as the monitored environment grows, one might run into performance problems. A full Zabbix performance discussion is out of scope here, but let's discuss the starting points to having a healthy configuration and the directions for further research:

  • Monitor only what you really need, as rarely as possible, and keep the data only for as long as really needed. It is common to new users of Zabbix to use default templates as-is, add a lot of new items with low intervals...and never look at the data. It is suggested to clone the default templates, eliminate all that is not needed, and increase the intervals as much as possible. This involves trimming item lists, increasing intervals, and reducing history and trend-retention periods. There are also events, alerts, and other data—we will discuss their storage settings a bit later.

  • When using Zabbix agents, use active items. Active items will result in a smaller...
