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. You will be able to organize your data in the form of graphs and charts along with building intelligent triggers for monitoring your network proactively. Toward the end, you will gain expertise in monitoring your networks and applications using Zabbix. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: Zabbix Network Monitoring-Second Edition Zabbix Cookbook Mastering Zabbix-Second Edition

Tying it all together


So, we found out that a normal or passive agent waits for the server to connect, while an active agent connects to the server, grabs a list of items to check, and then reconnects to the server periodically to send in the data. This means that using one or the other kind of Zabbix agent item can impact performance. In general, active agents reduce the load on the Zabbix server because the server doesn't have to keep a list of what and when to check. Instead, the agent picks up that task and reports back to the server. But you should evaluate each case separately: if you only have a few items per host that you monitor very rarely (the update interval is set to a large value), converting all agents to active ones that retrieve the item list more often than the items were previously checked won't improve Zabbix server performance.

Note

It is important to remember that you can use a mixture of various items against a single host. As we just saw, a single host can have normal...
