Transaction Monitoring behavior on triggering alerts


   i just want to know how the alerting system works for transaction monitoring in Pingdom.

I've a transaction monitoring created for a website scenario which is set the interval time to check every 60 minutes. the question is I have to wait 60 minutes to receive successful alert even all the checks/steps come into green/successful with in few minutes or immediately. is there any possibility if i can get the successful alert(closed alert for the issue) as well as see them in green on dashboard immediately. Thanks in advace.
