Did anybody look for a bad guy who deleted an article you had almost finished after a month of work? Now it's difficult to find such person. Analyzing Apache, PHP and MySql logs is difficult and may be inconclusive. Did XOOPS team think about implementing a system logging facility? I think about something that would register events triggered in the system and would contain information like:

- user name
- user IP
- module name
- item ID
- event name
- event description, parameters etc.

In next stages some log levels could be implemented.

I realize it will be a big task, affecting both core and modules, but maybe it is worth to show tha way to do it?

I am in the planning phase of a Hook system for XOOPS, allowing modules to trigger events and respond to them.

With this system in place, it should be easy for modules to trigger events such as additions, updates and deletions of items - and configure a Log module to respond to these events and gather the information, you described.
