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.

Certificate-based encryption


With PSK-based encryption protecting our sensitive Zabbix trapper item, let's move to certificates. We will generate certificates for the Zabbix server and agent and require encrypted connections on the Zabbix agent side for passive items. Certificate authorities sign certificates, and Zabbix components can trust one or more authorities. By extension, they trust the certificates signed by those authorities.

You might have a certificate infrastructure in your organization, but for our first test, we will generate all required certificates ourselves. We will need a new certificate authority (CA) that will sign our certificate. Zabbix does not support self-signed certificates.

Tip

It is strongly recommended to use intermediate certificate authorities to sign client and server certificates—we will not use them in the following simple example.

Being our own authority

We'll start by creating the certificates in a separate directory. For simplicity's sake, let's do this...
