How to confirm when a user last used RStudio Server ?

Hello,

In regards to estimating/managing licensing costs, I'm wanting to to confirm the last login time for every user that has access to our RStudio Server Pro system (2024.09.1 on RHEL 8).

I had a look at the last and lastlog commands within RHEL 8, but they don't seem to align with RStudio Server active sessions in the admin dashboard.

Any advice on how to achieve this, or suggestions on logging configurations to start obtaining this information?

Thanks
Stuart
