### VMware Monitoring Setup Example

Source: https://www.zabbix.com/documentation/current/en/manual/vm_monitoring/vmware_json

Illustrates a practical setup example for VMware monitoring in Zabbix, likely involving configuration of hosts, items, and potentially low-level discovery rules.

```text
1. Configure Zabbix server to connect to vCenter.
2. Create a host in Zabbix representing the vCenter or individual ESXi hosts.
3. Add items using the VMware item keys to collect desired metrics.
4. For automatic discovery of VMs, configure Low-Level Discovery (LLD) rules using VMware-specific LLD macros and JSONPath.
