Radius Manager alternative

Using radius manager but it has a very annoying short coming !

Its session based so it does not give daily usage reports, so a user could have a session of 30 days giving total usage only and no daily breakdown ?

But whats strange is the connection tracking module by them gives a daily connection tracking report ?

I have had to run a script to disconnect ppp sessions daily and this will give a daily report - downside it interrupts a user internet service while a new session is established,

So my question can anyone recommend an alternative that will give daily usage reports or even one that could run side by side with RM
