SSH Connection Accounting

[Tito Mari Francis Escaño]

Good day!
I'm googling for resources on SSH connection accounting and unfortunately
for me, I keep bumping into Cisco-related resources online. What I need to
know is how to determine the SSH connection accounting per user, like if a
user is currently connected, when a user connected, how long the SSH session
took if successfully connected and maybe other related information.
I hope you can provide me pointers on this. Thanks!
