Log how many times an item has been opened

Hello,

we are looking into measuring how much items/modules are beeing used by our users.

I think if you add a client method to a item, that should be no problem with an OnShowItem event and then increase a number on a table somewhere.

But is there are global approach that we don't have to insert such a method in each item we want to track?

Any ideas are welcome,

thanks in advance.
