Track log on, log off times
We are looking for some software accessible by all staff that can track users log on and log off times.
This is so the ICT teacher can track how long a certain exam accounts have been used for. Previous we used a bespoke bit of software that sat on the proxy server; however we have changed this now.
I know software like impero does this but we are looking for cheap or free? I know we can script this but would like a nice friendly interface for staff to use.
