This chapter focused on what is usually considered the core business of a monitoring system—its triggering and alerting features. By concentrating separately and alternately on the two parts that contribute to this function—triggers and actions—it should be clear to you how, once again, Zabbix's philosophy of separating all the different functions can give great rewards to the astute user. You learned how to create complex and sophisticated trigger conditions that will help you have a better understanding of your environment and have more control over what alerts you should receive. The various triggering functions and options as well as some of the finer aspects of item selection, along with the many aspects of action creation, are not a secret to you now.

In the next chapter, you will explore the final part of Zabbix's core monitoring components: templates and discovery functions.
