Adding additional syslog server to a host

I've written the following script to pull a list of hosts that already have some existing syslog servers configured and to add a new one however i keep getting the error "Unable to configure syslog server information for host 'xxx.xx.xxx'..... InnerText: No Root object set for output. The command did not provide proper output.implementation error!" 

Any idea where i have gone wrong? 

 

function ConfigureSyslog {

Write-Host

$txtlocation = Read-Host " Please enter txt file location"

write-host

write-host " Syslog server format   UDP://X.X.X.X:514" -ForegroundColor Yellow

$SyslogServer = Read-Host " Please enter syslog server"

 

$GlobalSysLogConfig = @()

 

ForEach ($esxhost in (Get-Content $txtlocation))

{

if((Get-VMHost $esxhost | Get-VMHostSysLogServer).Host -notcontains "$SyslogServer"){

 

         $EsxSysLogConfig = "" | select Host, Config, Time, Change

 

         Write-Host ".... Writing existing configuration of host $esxhost to log" -ForegroundColor Green

         $EsxSysLogConfig.Host = (Get-VMHost $esxhost).Name

              $EsxSysLogConfig.Config = (Get-VMHost $esxhost | Get-VMHostSysLogServer)

         $EsxSysLogConfig.Time = $(get-date -f yyyy-MM-dd-hhmm)

         $EsxSysLogConfig.Change = "Existing"

         $GlobalSysLogConfig += $EsxSysLogConfig

 

         $CombineConfig = $EsxSysLogConfig.Config +$SyslogServer

 

              Write-Host ".... Adding $SyslogServer to configuration on host $esxhost" -ForegroundColor Green

              Get-VMHost $esxhost | Set-VMHostSysLogServer -SysLogServer "$CombineConfig" -Confirm:$false

         $EsxSysLogConfig.Host = (Get-VMHost $esxhost).Name

              $EsxSysLogConfig.Config = (Get-VMHost $esxhost | Get-VMHostSysLogServer)

         $EsxSysLogConfig.Time = $(get-date -f yyyy-MM-dd-hhmm)

         $EsxSysLogConfig.Change = "Changed"

         $GlobalSysLogConfig += $EsxSysLogConfig

        

}

else{

    Get-VMHost $host | Get-VMHostSysLogServer | export-csv -path ".\Syslog Config.csv" -append

    Write-Host "$esxhost is already configured with $SyslogServer, moving on..." -ForegroundColor Red

       Start-Sleep -Second 1

    $EsxSysLogConfig.Host = (Get-VMHost $esxhost).Name

    $EsxSysLogConfig.Change = "No Change"

 

    $GlobalSysLogConfig += $EsxSysLogConfig

       }

}

}

Change this line:
Get-VMHost $esxhost | Set-VMHostSysLogServer -SysLogServer "$CombineConfig" -Confirm:$false

to:
Get-VMHost $esxhost | Set-VMHostSysLogServer -SysLogServer $SyslogServer -Confirm:$false

That specific error has been mentioned before.
There were a number of possible reasons:

- name resolution for the syslog server was not working on the ESXi node
- the connection to the remote syslog server was not working 
- the local syslog folder was incorrect (for example a disconnected LUN).


Update: I found an older reference to that same error.
See Solved: Cannot set Syslog.global.logHost either by GUI or ... - VMware Technology Network VMTN

If I don't use $CombineConfig, it removes the existing configuration. I can try $CombineConfig without the quotation marks though?

quotation marks do not make a difference here. What LucD mentioned might be the reason. 

Or

try this $CombineConfig = "$EsxSysLogConfig.Config,$SyslogServer"
