Overview of this book

Zabbix 4 Network Monitoring is the perfect starting point for monitoring the performance of your network devices and applications with Zabbix. Even if you’ve never used a monitoring solution before, this book will get you up and running quickly. You’ll learn to monitor more sophisticated operations with ease and soon feel in complete control of your network, ready to meet any challenges you might face. Starting with the installation, you will discover the new features in Zabbix 4.0. You will then get to grips with native Zabbix agents and Simple Network Management Protocol (SNMP) devices. You will also explore Zabbix's integrated functionality for monitoring Java application servers and VMware. This book 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 will understand how to optimize and improve performance. Troubleshooting network issues is vital for anyone working with Zabbix, so the book also helps you work through any technical snags and glitches you might face. By the end of this book, you will have learned more advanced techniques to fine-tune your system and make sure it is in a healthy state.

Using Proxies to Monitor Remote Locations

The Zabbix server can do monitoring using lots of different methods: it can communicate with Zabbix agents, SNMP devices, and IPMI devices; run commands; and do a whole lot of other things. A problem arises when the number of devices to be monitored increases; a single endpoint (our Zabbix server) is supposed to communicate with lots of others, and a large number of connections can cause problems both on the Zabbix server and in the network components between the Zabbix server and monitored devices.

It gets worse if we have to monitor remote environments—be it a branch office, another data center, or a customer site. Zabbix agents? Port 10050 must be open to all servers. SNMP? Port 161 must be open to all devices. It becomes unmanageable really quickly.

A solution is to use Zabbix proxies. A Zabbix proxy is a remote data-collector...
