# AIX by Zabbix agent

## Overview

It is an official AIX template. It requires Zabbix agent 7.0 or newer.


## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- AIX 6.1

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.

## Setup

Install Zabbix agent on the AIX OS according to Zabbix documentation.


### Macros used

|Name|Description|Default|
|----|-----------|-------|
|{$AGENT.TIMEOUT}|<p>The timeout after which agent is considered unavailable. It works only for the agents reachable from Zabbix server/proxy (in passive mode).</p>|`3m`|
