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.

Starting with the Zabbix API

The approaches we looked at earlier—direct database edits and XML import/export—were either risky or limited. Editing the database is risky because there is very little validation, and upgrading to a newer version of Zabbix can change the database schema, making our tools and approaches invalid. XML import/export was nice, but very limited—it did not allow modifying users, network discovery rules, actions lots, and lots of things in the Zabbix configuration.

This is where the Zabbix API could help. It is a JSON-based interface to Zabbix configuration and data. It offers way more functionality than XML import/export does, although there are still bits and pieces of configuration that cannot be controlled using it.

The Zabbix API currently is frontend based: it is implemented in PHP. To use it, we connect to the web server running the frontend and issue our requests. There are a lot of ways to do this, but here, we will try to do things in a manner that is language...
