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.
