Something I ran into when we added our Orion SQL instance to SAM:
The "AppInsight for SQL: Alert me when my database file is running low on space" alert fired on the file "SolarWindsFlowStorage_NTAFLOWMEMORYSTORAGE" in the "SolarWindsFlowStorage" database.
That file is a "FILESTREAM Data" file, and thus the file growth/free space that monitor/alert is for don't apply unless a "MaxSize" has been set on the file (which isn't the case by default or in our environment).
I was able to duplicate the out of the box alert to exclude it, but correcting the out of box alert would be best (as I'm sure more customers will encounter this as they move to NTA 4.4)
