In this chapter, we will talk about how the Zabbix frontend works and where to find the most important things in the interface and all the things that set Zabbix apart from the others. We will explain how to acknowledge problems from triggers that were activated when problems were detected. We will see how we can customize the frontend to our needs and explain the definitions being used in Zabbix. Next, we will show you how the Zabbix architecture is set up, so that you have a better understanding of where to look when things go wrong. Towards the end of the chapter, we will show you how to get an easy overview of the latest data in Zabbix.
