Hi all, I have two questions around the alert subscription criteria that have been bothering me for a long time and I can't get my head around: I've created a alert subscription that basically states to send all alerts generated by a specific group of servers to a specific recipient. The recipient receives all the alerts but not the heartbeat failure alerts. These are generated as I receive them (I receive all critical alerts). Why would this be? Secondly, I sometimes have to create quite specific alert subscriptions e.g. send all the alerts generated by the servers in group x but exclude any IIS alerts. How can this be achieved (exceptions in alert criteria)? Your help would be appreciated! Thanks AvdV

Hi 1. The Agent Health Service "Class" is a seperate entity from and completely unrelated to the computer class. You need to make sure you add the health service object to the group as well as the computer object. http://www.scom2k7.com/dynamic-computer-groups-that-send-heartbeat-alerts/ 2. I believe this is similar to views which only allow "includes" - Jonathan Almquist provided a great explanation on another thread a while ago, - note that this applies to VIEWS "it is not possible to exclude objects that match a pattern in your view expression. Expressions are sent to the RMS/DB in the form of a T-SQL literal expression (wrapped in a WHERE X LIKE 'your pattern'). You could actually see this in action if you were to attach a SQL Profile Trace while navigating to a view. So, one of the limitations of creating views in the Operations Console is that we can only include objects WHERE X LIKE 'your pattern'." - I think subscriptions work in a similar way where you can only use Includes (but am open to being corrected!). This means chosing classes \ groups appropriately but makes creating workflows likey you would like quite time consuming from an administrative perspective.
