Mapping Asset Groups - Why?

Hi All,

 

Low level query here.

When a map has completed, one can add assets to a group, scan etc....... From a discovery perspective, I totally understand this.

For the purpose of this query, lets assume I ran a map covering 10.10.10.0/24. The Network breakdown is:

10.10.10.1-10.10.10.19 = Servers

10.10.10.20-10.10.10.29=Switches

10.10.10.30-10.10.10.39=Printers

10.10.10.40-10.10.10.49=Desktops

10.10.10.100-10.10.10.149=Laptops (DHCP Assign Addresses.

The reason for the discovery is:

1. Find ALL Devices within the whole /24 subnet

2. Create Asset Groups from devices found

3. Ensure assets are in the correct IP Range

4. Scheduled to run Weekly

The results come back with 10 Servers (.1-.10), 2 Switches, (.20,.21) and 50 Laptops (.100-.149). (No printers found, no Desktops found - Results were as expected (In this example))

I now have a discovery of a simple subnet. I add the assets to 3 New Asset Groups - Servers, Switches, Laptops. Happy days.

Server asset group now contains 10 assets reflecting the above IPs .1-.10. and so on.

 

My query is this: When I look to run a new map, one option is to discover based on Asset Group. I'm curious - Why would I want to select (For example) Servers Assets Group which only contains the 10 servers I already know about and theoretically should only return the exact same assets as it will only "discover" the IP's already discovered and approved/added to our subscription? To find "more" assets I would need to run my map against a wider IP Range (10.10.10.1-10.10.10.19, to see if more servers have "appeared" in the first 20 available addresses for example). Without this I am surely getting nothing new?

 

Just curious as to why the option of Assets Groups is there within Maps and the benefit of mapping a known group.......

 

Opinions please.
