.DESCRIPTION
|
||||
This Function collects Basic vSphere Informations for a Hardware Sizing Recommandation. Focus is in Compute Ressources.
|
||||
|
||||
.Example
|
||||
Recommend-Sizing -ClusterNames Cluster01, Cluster02 -Stats -StatsRange 60 -Verbose
|
||||
|
||||
.Example
|
||||
Recommend-Sizing -ClusterNames Cluster01, Cluster02
|
||||
|
||||
.Example
|
||||
Recommend-Sizing -ClusterNames Cluster01
|
||||
|
||||
.PARAMETER ClusterNames
|
||||
List of your vSphere Cluser Names to process.
|
||||
|
||||
.PARAMETER Stats
|
||||
Enables Stats Collection.
|
||||
|
||||
Warning: At the moment this is only fully tested with vSphere 5.5 and vSphere 6.5!
|
||||
|
||||
.PARAMETER StatsRange
|
||||
Time Range in Minutes for the Stats Collection.
|
||||
Default is 24h.
