VMWare View API - VirtualCenterHealth - Session is not authenticated

Jump to solution

Hi all,

To monitor our Horizon infrastructure with PRTG, I created some custom made scripts that use powerCLI and the ViewAPI. Suddenly, yesterday some of them stopped working and I have no idea what caused it, nor how to solve it. I'll list the script and the output. Hopefully someone can help me out? (the script output has been limited for readabliity)

Thanks a lot for any ideas.

Michiel.

Script:

# import necessary modules

Import-Module VMware.VimAutomation.Core

Import-Module VMware.VimAutomation.HorizonView

# connect to Horizon View Connection Server

$con = Connect-HVServer -Server "<view connection server>"  

#get Connection server information  

Write-host "**************************"

Write-host "Get Connection Server information"

$viewAPI = ""

$viewAPI = $Global:DefaultHVServers.ExtensionData.ConnectionServerHealth.ConnectionserverHealth_List()

$viewAPI

write-host ""

#get VCenter information

Write-host "**************************"

Write-host "Get VirtualCenter information"

$viewAPI = ""

$viewAPI = $Global:DefaultHVServers.ExtensionData.VirtualCenter.VirtualCenter_List()

$viewAPI

write-host ""

#all commands above work fine without problems

#following commands give an authentication error

#get VirtualCenterHealth_List information

Write-host "**************************"

Write-host "Get VirtualCenter Health information"

$viewAPI = ""

$viewAPI = $Global:DefaultHVServers.ExtensionData.VirtualCenterHealth.VirtualCenterHealth_List()

$viewAPI

write-host ""

#get ESX Hosts from vCenters

Write-host "**************************"

Write-host "Get ESX Hosts information"

$viewAPI = ""

$viewAPI = $Global:DefaultHVServers.ExtensionData.VirtualCenterHealth.VirtualCenterHealth_List().HostData

$viewAPI

write-host ""

#get Datastores from vCenters

Write-host "**************************"

Write-host "Get Datastores information"

$viewAPI = ""

$viewAPI = $Global:DefaultHVServers.ExtensionData.VirtualCenterHealth.VirtualCenterHealth_List().DataStoreData

$viewAPI

write-host ""

Disconnect-HVServer $con

For anyone who has the same problem, we still have it from time to time.

I've been able to narrow it down to some kind of change or service restart on the vCenter side.

It can be solved by restarting the Horizon View Connection server service on the connection server we are running the script against.

Regards, Michiel.

Just want to let you know that is has been solved, however, I'm still waiting on an answer form our vCenter experts about what they've done to solve this...

Answer from our vCenter experts: we didn't do anything...

But the same problem is back today.

I also noticed the same/similar message in the Horizon Admin/Console: Could not list datastores from VC

I cannot choose a new snapshot or parent VM for a desktop pool, because apparently I don't have access to the datastores anymore...

Any ideas?

Thanks,

Michiel.
