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.

Proxy benefits


With our first proxy configured, let's discuss in more detail its operation and the benefits it provides. Let's start with the main benefits:

  • A proxy collects data when the server is not available

  • A proxy reduces the number of connections to and from remote environments

  • A proxy allows us to use incoming connections for polled items

We talked about the proxy retrieving configuration data from the server, and we talked about it having a local database. The Zabbix proxy always needs a local database, and this database holds information on the hosts the proxy is supposed to monitor. The same database also holds all the data the proxy has collected, and if the server cannot be reached, that data is not lost. For how long? By default, data is kept for one hour. This can be configured in the zabbix_proxy.conf file, the ProxyOfflineBuffer parameter. It can be set up to 30 days, but beware of running out of disk space, as well as of the potential to overload the Zabbix server when connectivity...
