Good question. It's not a command I use very often. Most of the time I wipe computers individually, though it is easier to do it through Jamf. I've had situations in the past where I used the "wipe computer" command and it completely wiped it to the point where the OS was practically removed and I had to reinstall using a bootable drive. I've also had a few instances (yesterday for example) where I've wiped the computer but it simply set it back to a factory default state. I would test it on one of them and see what would happen.
As far as a record in Jamf, the only place where I see a record of Jamf reporting that it was wiped (using the computer I wiped yesterday with the "wipe computer" as an example), is in the History tab when you look in the Management History section. I'm not sure if this is the kind of record that you're looking for but I've included a screenshot so you can see what it looks like for me. Plus, as long as you don't delete the computer record in Jamf, you should always have this computer to refer back to. We even still have some old records of computers that we've released from Apple School Manager accessible in Jamf. Hope this helps!
