For scenario 1 - you can create a blackout for the alarms [URL]  For scenario 2 - you need to check if you are sized for the added monitored vcenter first so your overall monitoring is not impacted by the added objects/metrics/alerts. As far as adding a vcenter, you do that from the Virtual Environment Dashboard > Administration tab. Follow these instructions [URL] Hope this helps Golan 
Hi  i know I have been asking some quite simple and silly questions these days, but believe me I have been given this foglight tool to setup in our environment which I have no idea of, but no other go.. have to do it. so trying my ways. Scenario 1: I have 3 vCenters currently being monitored in my FVE 8, we are going to do maintenace on one vCenter, how do I stop all the alerts for that specific vCenter. Do I need to amend each and every rule or is there any way to stop the agent which collects the data..something like that.  Scenario 2 : I want to add a new vCenter environment to my existing Foglight tool, how can that be achieved.  Your quick response will be much appreciated. Thanks Regards, Eager 2 Learn
