Ok. So, are you saying here that when apache-svc goes down too, you will not
receive any notifications anymore related to apache-svc?
I think this matrix will help me better:
apache-svc=UP, mysql-svc=DOWN - What notification should I get?
apache-svc=DOWN, mysql-svc=DOWN - What notification should I get?
apache-svc=DOWN, mysql-svc=UP - What notification should I get?
Please bear with me for now. :)
Thanks again.
