Download logs from all esxi host to desktop to review it later

I got some issue within my virtual environment, and found something suspicious in the ESXi logs.

But due to limited time I was not able to review the logs on the other esxi server. here I have created a script to download logs from all esxi host to your desktop or shared location. which will be helpful to review them later. 

I have used pscp.exe (kept under c:\windows\system32 folder) tool to connect to download logs.

  foreach ($ip in $iplist) {   
   mkdir "c:\temp\logs\$ip"  
   cd "c:\temp\logs\$ip"  
   $SSHservice = Get-VMHost $ip | Get-VMHostService | where {$psitem.key -eq "tsm-ssh"}   
   if ($SSHservice.Running -eq $False) {   
    Get-VMHost $ip | Get-VMHostService | where {$psitem.key -eq "tsm-ssh"} | Start-VMHostService     
   }   
   
   $filesource = "/var/log/*"   
   $filedestination = "c:\temp\"  
   $source = $filedestination+$ip+"\vmkwarning.log"  
   $remoteserver = $user+"@"+$ip  
   $destination = $remoteserver+":"+$filesource  
   $dot = "."  
   Write-output "y" | pscp.exe -r -pw $password $destination $dot  
   Get-VMHost $ip | Get-VMHostService | where {$psitem.key -eq "tsm-ssh"} | Stop-VMHostService -Confirm:$false  
  }
