This script proved to be a little more challenging than I had first expected. As you may be aware, simply running Set-VMHostSysLogServer will overwrite your existing configuration which is less than ideal when you’re trying to add a new server to your list.
This script will prompt you for a file that will need to contain a list of all hosts you want to configure, it will also prompt you to supply the Syslog server address in UDP://X.X.X.X Format or using s FQDN.
