Advice regarding statistics

Hello.

Can anyone recommend a good statistics mod/plug-in for vBulletin 3.6.4? I look after a large forum for a company, and they are asking for detailed useage statistics not covered by vB's default stats.

These are the kind of stats I'm looking for:
- New posts per parent/child forum between x and y dates
- New threads per parent/child forum between x and y dates
- Active users per parent/child forum between x and y dates
- Most popular threads per parent/child forum between x and y dates
- Most popular parent/childforums between x and y dates
etc.

I guess the key is being able to determine which forums you want to include in the statistics - either a specific child forum, a parent forum or category, or the whole site.

I've run a search on the forums but can't quite find anything that does what I'm looking for (maybe my search was bad or I just missed some). Any help, recommendations or pointers in the right direction would be much appreciated.

Thank you!
