Pro Tips with Esben #9
Managing a complete IT environment can be a challenge due to the numbers involved alone. When dealing with thousands of assets, how do you really know when you’re scanning successfully?
IP Locations
Since networks are already organized, why not use that to our advantage. The first step is to set up your IP locations. IP location lets you create an asset group based on an IP range, perfect for mapping your assets to their subnets. Additionally, this also gives us the benefit of knowing exactly how many assets we have in each subnet. To configure your IP locations you can navigate to ConfigurationAsset Groups.
Measure Success
To measure our scanning success I’ll be using three metrics. The total number of assets, assets scanned successfully and assets scanned unsuccessfully.
The total is pretty simple, counting every asset and which IP location they are a part of. For the successful assets, we count all assets where the last seen scanned time is equal to the last tried scan time. For the number of failed assets, we count all assets where the last seen isn’t equal the to last tried or where the last seen doesn’t exist.
The result is that we get an overview of all of our IP locations, how many assets they contain and how successful scanning is. By analyzing the data, you can make more informed decisions on where you need to focus next to improve your scanning or if there are subnets that don’t need scanning at all.
