short_description: Gathers facts about remote ESXi hostsystem
description:
- Gathers facts about remote vmware host.
- This module can be used to gathers facts like CPU, memory, datastore, network and system etc. about ESXi host system.
- Please specify hostname or IP address of ESXi host system as C(hostname).
- If hostname or IP address of vCenter is provided as C(hostname), then information about first ESXi hostsystem is returned.
