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 that can disrupt an efficient and healthy IT department. This course is for administrators who are looking for an end-to-end monitoring solution. It will get you accustomed with the powerful monitoring solution, starting with installation and explaining the fundamentals of Zabbix. Moving on, we explore the complex functionalities of Zabbix in the form of enticing recipes. These recipes will help you to gain control of your infrastructure.

Understanding high availability


High availability is an architectural design approach and associated service implementation that is used to guarantee the reliability of a service. Availability is directly associated with the uptime and usability of a service. This means that the downtime should be reduced to achieve an agreement on that service.

We can distinguish between two kinds of downtimes:

  • Scheduled or planned downtimes

  • Unscheduled or unexpected downtimes

To distinguish between scheduled downtimes, we can include:

  • System patching

  • Hardware expansion or hardware replacement

  • Software maintenance

  • All that is normally a planned maintenance task

Unfortunately, all these downtimes will interrupt your service, but you have to agree that they can be planned into a maintenance window that is agreed upon.

The unexpected downtime normally arises from a failure, and it can be caused by one of the following reasons:

  • Human error

  • Hardware failure

  • Software failure

  • Physical events

Unscheduled downtimes also include...
