i cant creating alarm for vm deletion on vcenter level i think it isnt possible ? now i am looking for on vrealize operation manager. so for example i deleted a vm on vcenter and vrealize will send a email. is this possible on vrealize operation manager ?
Not possible to create an alert since this is not a metric in vRealize Operations Manager. If you have LogInsight then you can capture this event in the ESXi host logs as Alert Query and forward the same to vROps as an Alert.
Actually there is a metric you can use, "Removed Objects". You can combine this With alarms and make an alert function.
So in short, make a custom Group containing the VM Objects, and then use the "Removed Objects" metric to make an alert
