This article shows you how to practice Zabbix macro variables, the content is concise and easy to understand, it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

I. Introduction to Macro

A macro is an abstract concept (Abstraction) that replaces a certain text pattern according to a series of predefined rules, and the interpreter or compiler automatically does this pattern replacement when it encounters a macro. Similarly, zabbix saves the preset text pattern based on macros and replaces it with the text in it when called.

Second, use the scene

Host macro (HOST)-the highest priority, set directly on the host

Macros defined by the host template-followed by priority. If you have more than one template, the higher the template, the higher the priority of the macro (Template)

Global macros (checked last)

In other words, zabbix looks for the value of a macro, first check whether there is hosts, if not, then find the first template of the current host, if not looking for the second template, until the last template, if still not found, then the global macro will be used. If the global macro does not exist, the macro variable will not be replaced.

Macro variables are often used to replace accounts, ports, passwords, etc. For example, if you want to use an account or password for monitoring, you can define it as a macro. If the account password is changed next time, you only need to modify the macro. There is no need for every monitoring item to change the account password.

Naming conventions for macros: a combination of uppercase letters, arrays, and underscores that can only begin with uppercase letters.

3. Built-in {MACRO}

You don't need to add $to quote:

Zabbix has many built-in macros, such as {HOST.NAME}, {HOST.IP}, {TRIGGER.DESCRIPTION}, {TRIGGER.NAME}, {TRIGGER.EVENTS.ACK}, and so on.

Give an example of some macros:
