Export / Download user activity logs


I would like to download the complete logs of my Elgg community for offline analysis. I refer to the logs ones I can search and browse with Log Browser. I haven't found a way to do that yet. Can anyone please suggest a way to achieve that?

I've just started using the new excelanalytics plugin, but it only provides a downloadable log of new activity on the website, so I need something else to download all past information.

Thanks for your help!
