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.

Overview


For Zabbix communication encryption, two types are supported:

  • Pre-shared key

  • Certificate-based encryption

The pre-shared key (PSK) type is very easy to set up but is likely harder to scale. Certificate-based encryption can be more complicated to set up but easier to manage on a larger scale and potentially more secure.

This encryption is supported between all Zabbix components—server, proxy, agent, and even zabbix_sender and zabbix_get.

For outgoing connections (such as server-to-agent or proxy-to-server), only one type may be used (no encryption, and PSK or certificate-based). For incoming connections, multiple types may be accepted. This way, an agent could work with encryption by default for active or passive items from the server and then work without encryption with zabbix_get for debugging.

Backend libraries

Behind the scenes, Zabbix encryption can use one of three different libraries: OpenSSL, GnuTLS, or mbedTLS. Which one to choose? If using packages, the easiest and safest is...
