Unable to get correct information from multiple vCenters

[ganapa2000]

Hi,

I am unable to get the correct correct information when running for multiple vCenters. I get the correct information, if I run against one vCenter but when I run against multiple vCenters I am getting incorrect info

Please help!!

$vCenters = @(
"vcenter1"
"vcenter2"
"vcenter3"
)
Connect-viserver -Server $vCenters

$report = Foreach ($vc in $global:DefaultVIServers)

$Output = @()
Get-Cluster | %{
$hypCluster = $_
## get the GenericMeasureInfo for the desired properties for this cluster's hosts

What do you mean by "incorrect info"?

Note that depending on your setting of DefaultVIServerMode, a cmdlet like Get-Cluster without a Server parameter, might return all clusters from all vCenters that you are connected to.

[ganapa2000]

LucD,

The Host count, CPU and Memory count shows more than that is present in the each vcenter

[LucD · Accepted solution]

Start by using the Server parameter on the cmdlets

[ganapa2000]

LucD,

I tried as below, still no luck 😞

$vCenters = @(
"vCenter1"
"vCenter2"
"vCenter3"
)
Connect-viserver -Server $vCenters

$report = Foreach ($vc in $global:DefaultVIServers)
{
$Output = @()
Get-Cluster -server $vc | %{
$hypCluster = $_
## get the GenericMeasureInfo for the desired properties for this cluster's hosts

$temp= New-Object psobject

You didn't use the Server parameter on the Get-View cmdlet

LucD,

After making the changes as suggested, I am output from 1st vcenter and other two vcenters info is missing in the report

What are you actually storing in $report?

Also, you are overwriting that same worksheet in the XLSX each loop.

LucD,

After I made the changes as below, it is now working as expected. Thanks for your help 🙂

Let me know, if this is correct.
