This idea is fantastic please add this.
Problem: I have a new volume added to a server how do I have solar winds automatically monitor this or at least alert me I have a new hard drive (maybe I do not want to monitor it). I also may have hundreds of servers with an existing volume or two that I do not want to monitor. Going through a discovery's ignore list for hundreds of servers will be VERY time consuming.
So in a nutshell - I have servers that I do not monitor all volumes. I add a new volume I want to monitor. How do I have solar winds alert me that I have a new volume not being monitored and NOT include the fact that I have other volumes not being monitored because I don't care about all of them.
Solution: On your dbo.DiscoveredVolumes (and dbo.DiscoveredInterfaces) tables. (might as well do this for all resource types..). Add a column - 'InitialDiscoverDate' When I run my scheduled discovery on my server network - it will populate this column with that date/time. This column for each row (each row being a discovered volume of course) is not changeable. Once it gets data a new discovery does NOT override this column. (Maybe add a column for 'InitialDiscoveryDate' and 'LatestDiscoveryDate') although at this time I cannot think of a good reason to keep the latter..but maybe it creates the flexibility now that we have it.
So - now I have a column with my 'InitialDiscoveryDate' I run my discovery to Create a baseline if you will to populate this column. Now any subsequent discovery can be 'filtered' on this column so if I run weekly discoveries I can now say 'Only include items discovered after X date' Now I have a nice and clean report showing servers with new volumes, interfaces, whatever. No huge report where I have to add to an ignore list. I can check from this scan the volumes, interfaces, etc to add to the SW monitoring.
Sure using the ignore list with a small amount of servers is fine - but for your Enterprise customers (customers with HUNDREDS+ servers) using the ignore list is not feasible. If I had this column of dates I could filter on a date and easily see only deltas for this data and quickly add new resources to my monitoring.
