i want grid to use out of box monitoring for all targets, but when it comes to email notifications i want to recieve notification only for subset of those items ( as well as couple of different items which are not enabled as part of out of box monitroing),
what is this is best approach to implement this?
is bellow the only way and efficient way of doing it?
1. create template for each target types ( i.e host_temp, db_temp..) using existing "create like " button to clone existing templates provided by oracle such as "Oracle provided Host template" , I assume this is the template oracle used for out of box monitoring ? and then add my own metrics to the template.
2. create notification rules (one per target type) , limit rules to only those metrics which i want to be notified
Yes, that is the general way to do it.
