I have a simple query in Log Analytics set up as an Alert to test it. For I understand it should fire every 5 minutes, because at least 1 IIS request has been made for the past 5 minutes. Yet this Alert Rule never triggers... Am I doing something wrong? query
Solution: I found the problem, so apparantly you have to set an Action Rule as well. After creating one the Alert started firing. I don't know if this is intended, because Action Rules are in preview atm
