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

Summary


Having explored basic monitoring with a Zabbix agent before, we looked at a major agentless monitoring solution in this chapter—SNMP. Given the wide array of devices supporting SNMP, this knowledge should help us with retrieving information from devices such as printers, switches, UPSes, and others, while also listening and managing incoming SNMP traps from those.

Beware of starting to monitor a large number of network devices, especially if they have many interfaces. For example, adding 10 switches with 48 ports, even if you monitor a single item per switch once a minute only, will make Zabbix poll eight new values per second (480 ports once a minute results in 480/60=8 new values per second). Usually, more values per port are monitored, so such an increase can bring a Zabbix server down and severely impact network performance even when SNMP bulk get is used.

While we have created several hosts by now, we only paid attention to the host properties that were immediately useful. In...
