# VMware FQDN

## Overview

This template is designed for the effortless deployment of both VMware vCenter and ESX hypervisor monitoring and doesn't require any external scripts.

The "VMware Hypervisor" and "VMware Guest" templates are used in discovery and normally should not be manually linked to a host.
For additional information please check https://www.zabbix.com/documentation/7.0/manual/vm_monitoring

## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- VMware 6.0, 6.7, 7.0, 8.0

## 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

1. Compile Zabbix server with the required options (`--with-libxml2` and `--with-libcurl`)
2. Set the `StartVMwareCollectors` option in Zabbix server configuration file to "1" or more
3. Create a new host
4. If you want to use a separate user for monitoring, make sure that the user is a member of the `SystemConfiguration.ReadOnly` and `vStatsGroup` groups
Set the host macros (on the host or template level) required for VMware authentication:
```text
{$VMWARE.URL}
{$VMWARE.USERNAME}
{$VMWARE.PASSWORD}
```
5. Link the template to host created earlier

Note: To enable discovery of hardware sensors of VMware hypervisors, set the macro `{$VMWARE.HV.SENSOR.DISCOVERY}` to the value `true` on the discovered host level.
