*Grafana dashboard

For those using Grafana, I have uploaded dashboard to https://grafana.com/dashboards/4812. Note that your host must be in Zabbix host group VMware. 

Others

If template does not work, try using the official Zabbix VMware monitoring (e.g. https://www.zabbix.com/documentation/4.0/manual/vm_monitoring)
