We have recently seen virtual machine guests removed from NPM without notice. As we monitor this on a daily basis via a daily report of removed node events, were able to capture the time and review the IIS logs to determine that this was caused by de-selecting or unchecking "ESX Polling" on a VMWare ESX Host. Is this expected behavior? If so, it seems like there should be some sort of warning that this is going to occur.
I will continue digging into this, but I'm curious to find out if this has happened to others and/or if everyone but me knows that this is what is "supposed to happen".
Thanks for your feedback,
