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

Querying WMI


Besides built-in support for performance counters, the Zabbix agent also supports WMI queries.

Note

Zabbix supports WMI through the Zabbix agent—remote WMI is not supported at this time.

To extract some useful information, we need a WMI query, and we might want to test the queries quickly—that can be done in Windows or by using the Zabbix agent. On the Windows side, the wbemtest.exe utility can be used. When launching it, click on Connect, accept the default namespace of root\cimv2, and click on Connect again. Then, in a dialog like this, click on Query:

You can enter complete queries here. For example, we could ask for the current time zone with a query:

SELECT StandardName FROM Win32_TimeZone

An alternative way to test such queries through the Zabbix agent would be with the zabbix_get utility, discussed in Chapter 3, Monitoring with Zabbix Agents and Basic Protocols.

With the query available, we can proceed with creating an item. Navigate to Configuration | Hosts, click on Items...
