Answer 1

You could install either LambdaProbe or it's fork PSIProbe which will give you details such as this. Both are open source products and usage is very similar to the Tomcat Manager.

LambdaProbe does not seem to be maintained any more. But see the session list screenshot for PSIProbe, you can see the Age and IP of each session.

Answer 2

Make a HttpSessionListener, register it in web.xml (or with annotations, if using servlet 3.0).

the sessionCreated(..) method is triggered whenever a session is created.
