With some groups and hosts automatically created, let's see what data they're collecting. Navigate to Monitoring | Latest data and select Hypervisors in the Host groups field. Then, click on Filter:

There'll be more items for each hypervisor. Some of them might not have data yet, but a bit of patience should reveal all of the details.

Now, filter by hypervisor virtual machine group in the Host groups field or by a single discovered virtual machine in the Hosts field:

Again, there should be more items, and some could still be missing values. They all should eventually get populated, though.

Once all of the LLD rules on the host level have run, we'll see quite a lot of items being covered by the default templates. In many cases, these templates might even be enough. Sometimes, you might want to extend them, though. The same as with other default templates, it's strongly suggested you clone the template first and then make the modifications to the new template.

But what other things could be supported besides the already included items? To see the full list of supported VMware item keys, visit the item type section in the Zabbix manual. VMware items are listed after Simple checks, and at the time of writing this, the full URL is https://www.zabbix.com/documentation/4.0/manual/config/items/itemtypes/simple_checks/vmware_keys. Why below Simple checks? That's the item type for all VMware keys. When adding new items, the type must be set to simple check. The same as other simple checks, these items are processed by the Zabbix server directly.
