Standardize source and path across management packs
For drive space alerts, "source" is the drive, "path" is the computer. SCOM hearbeat alerts use "source" as the computer and "path" as the SCOM namespace path. SQL has "source" as the instance name, and "path" as the computer\instance name, and AD sets both to computer name. It would be good if these were standardized; for example, "source" could be the computer with the problem, and "path" may be the SCOM namespace path. Or perhaps a new field could be added for the computer name.

Source is the instance of the targeted class for the workflow. The Path is the hosting path; the class that hosts the targeted class. This might seem like a flagrant plug (sortof) but there is a tool to generate a visual graph for SCOM class taxonomy which includes discovery and hosting relationships here: https://blogs.msdn.microsoft.com/tysonpaul/2018/08/06/scomhelper-powershell-module-a-scom-admins-best-friend/
