In the previous topic where we explained the frontend, we already talked a bit about hosts, triggers, items, and so on. So I am sure you have a lot of questions about what they are. Before we move on with our Zabbix book, I will first explain you a bit about the Zabbix definitions so that you have an idea what everything is.
By now you should have an up and running Zabbix configuration and you should know your way around the frontend. If you have no clue how the frontend works, then go back to previous topic and have a look at Exploring the frontend.
