Hi.
Username and Login- and Logout-Times are available in AE v10 itself. You can right-click the user object and select "Statistics" to get the data.
You can also get Logon- and Logoff data from the logfiles. You will also find the DNS machine name and AE client there. Like so:
grep -E "U0011852|U0003205" /path/to/ae/logdir/*.txt
[...]
20171027/173403.668 - U0011852 Logoff 'DEMOUSER' ('DEMOUSER/UC'), client: '0010' (Connection='*CP003#00001573', index='001' released).
20171027/173453.092 - U0003205 Logon of 'DEMOUSER' ('DEMOUSER/UC'), client: '0010' accepted by host 'DEMOCLIENT'. Client version = '10.0.8+hf.1.build.533
