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.

Chapter 4. Collecting Data

Now that you have a Zabbix installation that is properly sized for your environment, you will want to actually start monitoring it. While it's quite easy to identify which hosts and appliances, physical or otherwise, you may want to monitor, it may not be immediately clear what actual measurements you should take on them. The metrics that you can define on a host are called items, and this chapter will discuss their key features and characteristics. The first part will be more theoretical and will focus on the following:

  • Items as metrics, not for status checks
  • Data flow and directionality for items
  • Trapper items as a means to control the data flow

We will then move to a more practical and specific approach and will discuss how to configure items to gather data from the following data sources:

  • Databases and ODBC sources
  • Java applications, the JMX console, and SNMP agents
  • SSH monitoring
  • IMPI items
  • Web page monitoring
  • Aggregated and calculated items
