short_description: Gathers VMKernel facts about an ESXi host
|
|
description:
|
|
- This module can be used to gather VMKernel facts about an ESXi host from given ESXi hostname or cluster name.
|
|
version_added: '2.5'
|
|
author:

|
- Abhijeet Kasurde (@Akasurde)
|
|
notes:
|
|
- Tested on vSphere 6.5
|
|
requirements:
|
|
- python >= 2.6
|
|
- PyVmomi
|
|
options:
|
|
cluster_name:
|
|
description:
|
|
- Name of the cluster.
|
|
- VMKernel facts about each ESXi server will be returned for the given cluster.
|
|
- If C(esxi_hostname) is not given, this parameter is required.
|
|
esxi_hostname:
|
|
description:
|
|
- ESXi hostname.
|
|
- VMKernel facts about this ESXi server will be returned.
