[imp] Administrative features in IMP?

[Michael Marziani]

I've scoured the archives to no avail.

In IMP/Horde, how can I:

-See how many active sessions there are?
-See any additional information about the sessions (IP address, etc)?
-Build reports of logins, etc?

For page hits I can simply use apache's logs, but I have no idea how to
track php sessions and see how many I currently have active.  I am
trying to determine usage and build some reports for management.

Thanks for any assistance.
