Managing Alerts

by Andrea Dalle Vacche Stefano Kewan Lee | December 2013 | Open Source

Checking conditions and alarms are the most characteristic functions of any monitoring system, and Zabbix is no exception. What really sets Zabbix apart is that every alarm condition, or triggers—as they are known in this system—can be tied, not only to a single measurement but also to an arbitrary complex calculation, based on all of the data available to the Zabbix server. Furthermore, just as triggers are independent from items, the actions that the server can take based on trigger status are independent from the single trigger, as you will see in the subsequent sections.

In this article written by Andrea Dalle Vacche and Stefano Kewan Lee, authors of the book Mastering Zabbix, you will learn the following things about triggers and actions:

  • How to create complex, intelligent triggers
  • How to minimize the possibility of false positives
  • How to set up Zabbix to take automatic actions based on the trigger status
  • How to rely on escalating actions

The Magic

by Alex Knol | December 2013 | Open Source

It is time we explain some of the inner workings of Angular. Angular does some neat things for us. It saves us from having to write a bunch of boilerplate code. In this article written by Alex Knol author of the book Dependency Injection with AngularJS, we will see the magic of Angular.

Dependency Injection is baked into AngularJS and heavily used throughout. Another feature is a built-in subset of a jQuery functionality called jQLite. It contains all the necessary functions to make AngularJS run without jQuery and has the exact same interface. If jQuery is available in your application, it will be used instead. Angular also takes the burden of bootstrapping your application, which will be covered later in this article.
