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

Receiving SNMP traps


While querying SNMP-capable devices is a nice method that requires little or no configuration of each device in itself, in some situations, information flow in the reverse direction is desired. For SNMP, these are called traps. Usually, traps are sent upon some condition change, and the agent connects to the server or management station on port 162 (as opposed to port 161 on the agent side, which is used for queries). You can think of SNMP traps as being similar to Zabbix active items; as with those, all connections are made from monitored machines to the monitoring server.

The direction of the connections isn't the only difference—SNMP traps have some other pros and cons when compared to queries. For example, SNMP traps are usually more capable of detecting short-lived problems that might have been missed by queries. Let's say you are monitoring incoming voltages on a UPS. You have decided on a reasonable item interval that would give you useful data and wouldn't overload...
