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.

Active proxy, passive proxy


The Zabbix proxy first appeared in Zabbix version 1.6, back in 2008. Since then, it has proven to be a very good solution. When the Zabbix proxy first appeared, it supported connecting to the Zabbix server only, similarly to active agent. Zabbix version 1.8.3 introduced a capability of the server to connect to the proxy, and now active proxies and passive proxies are available. While the Zabbix agent can communicate with the server in both ways at the same time by having active and passive items on the same host, the Zabbix proxy communicates with the server only in one way at a time—the whole proxy is designated active or passive.

The proxy mode does not change the direction of connections to or from the monitored devices. If using active items through a proxy, the agent will still be the one making the connections, and if using passive items, the agent will be accepting connections. It's just that instead of the server, the agent will now communicate with the...
