Being a former ServersAlive user, I liked the option it had to do a 'second knock' just in case the host was either not really down, or came back up right away. In either case, I'm wondering if what I'm doing is working similar to this:
In my alert profile, the first thing I have is to 'check host again' after 1 'bad' status. Then i have my normal actions starting after 2 bad statuses. Is this the right way to go about this?
