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.

Summary


In this chapter, we covered a great and easily maintainable solution for larger-scale data collection—Zabbix proxies. Zabbix proxies are also very desirable for remote environments. Similar to Zabbix agents, Zabbix proxies can operate either in active or in passive mode, reducing the hassle with firewall configuration.

Let's recap the main benefits of Zabbix proxies:

  • Connections between the Zabbix proxy and the Zabbix server are done on a single TCP port, thus allowing us to monitor devices behind a firewall or devices that are inaccessible because of network configuration

  • The Zabbix server is freed up from keeping track of checks and actually performing them, thus increasing performance

  • Local buffering on the proxy allows it to continue gathering data while the Zabbix server is unavailable, transmitting it all when connectivity problems are resolved

Remember that active agents must point to the proxy if a host is monitored through that proxy. Passive agents must allow incoming connections...
