Overview of this book

Nowadays monitoring systems play a crucial role in any IT environment. They are extensively used to not only measure your system’s performance, but also to forecast capacity issues. This is where Zabbix, one of the most popular monitoring solutions for networks and applications, comes into the picture. With an efficient monitoring system in place you’ll be able to foresee when your infrastructure runs under capacity and react accordingly. Due to the critical role a monitoring system plays, it is fundamental to implement it in the best way from its initial setup. This avoids misleading, confusing, or, even worse, false alarms which can disrupt an efficient and healthy IT department. This new edition will provide you with all the knowledge you need to make strategic and practical decisions about the Zabbix monitoring system. The setup you’ll do with this book will fit your environment and monitoring needs like a glove. You will be guided through the initial steps of choosing the correct size and configuration for your system, to what to monitor and how to implement your own custom monitoring component. Exporting and integrating your data with other systems is also covered. By the end of this book, you will have a tailor-made and well configured monitoring system and will understand with absolute clarity how crucial it is to your IT environment.

Zabbix SNMP monitoring


Simple Network Monitoring Protocol (SNMP) may not be as simple as the name suggests; it's a de facto standard for many appliances and applications. It's not just ubiquitous—it's often the only sensible way in which one can extract the monitoring information from a network switch, disk array enclosure, UPS battery, and so on.

The basic architecture layout for SNMP monitoring is actually straightforward. Every monitored host or appliance runs an SNMP agent. This agent can be queried by any probe (whether it's just a command-line program to do manual queries or a monitoring server such as Zabbix) and will send back information on any metric it has made available or even change certain predefined settings on the host itself as a response to a set command from the probe. Furthermore, the agent is not just a passive entity that responds to the get and set commands but can also send warnings and alarms as SNMP traps to a predefined host when some specific conditions arise...
