If I understood you correctly, you want to have a report of all assets that have the 'last seen' date updated in the last 30 days. The 'last seen' field only gets updated when an asset is scanned successfully.
I have made a report for Windows computers that have been seen in the last 30 days, i.e. successfully scanned in the last 30 days. Instructions for adding this report to your Lansweeper installation can be found
here. If you are interested in building or modifying reports, we do recommend:
- Reviewing some SQL tutorials, as the Lansweeper report builder is a standard SQL editor. If you know SQL, you know how to build Lansweeper reports as well. This seems like a good tutorial.
- Making use of our database dictionary, which explains in great detail what each database table and field stores. More information on the dictionary can be found here.
