Appinsight for SQL: Filter and include component INSTANCE in alert

You can edit the template to exclude indexes below a certain size, which i usually set to a much higher threshold than they come out of the box because there is not really much performance impact to fragmented small indexes anyway.  I find that once you weed out all the ones that arent at least maybe 50mb or more then the list begins to become semi useful.  Taking it a step further, if you know you have all your defrag jobs scheduled and running in SQL tasks then is it even necessary to set a threshold within Orion on them at all?  It is an extremely odd situation where a DBA would decide that they have their defrag job scheduled tonight but things are looking sketchy this afternoon so we're going to defrag immediately.  If we have good processes in place I just remove the index fragmentation threshold completely.

To your B, it'd require a custom SQL/SWQL variable, but yes it is doable to get the name of the index that triggered the alert.
