I guess this is almost an AI module, as it would take a whole set of parameters (like Gábor said) and somehow classify the modules according to a certain "degree of use". The monitor could then issue some report about all modules below a certain threshold, to which it would expect a reaction from the site administrator wethere to mark them as "needed" or to disable them. This later reaction could even be a learning process for the classifier itself, or just a "don't mess with nuclear missiles" flag on that specific module, causing it to miss the next round of classifying.

I agree with Carl it is an administrative task and should be let to site Admins, but could the modules list page feature a "last used" timestamp column to help site admins know when it was the last time a module was used?
This info could be helpful for the auditing purposes James explained in his other posting.

I believe the original question is not whether a module is enabled or not but whether an enabled module is actually being used *at all.*

It's up to the site builder to pay attention and know the purposes of each enabled. To me this seems like is an administrative issue, rather than a technical issue.

I don't think you'd even need a module to do this. You can get a list of currently used modules by doing:

SELECT name FROM system WHERE type='module' AND status='1';

You could likely write a quick script to compare the list returned by that SQL statement to your modules list.

Thanks,

I have a list of 60+ modules that I download, via drush, to each new Drupal site that I build. I then enable whatever modules are needed for the specific site I'm working on as I carry out the build.

This means that once the site is launched, there may be modules that are not being called by Drupal core but that are still enabled and/or installed.

Is there an automated way - a specific module, for example - that will tell me which of the modules that are enabled on a site are being called by Drupal core?

Secondly, is there any performance implication for having lots of modules installed on a site if they are not enabled?

The answer to the second question seems to be "no". And It doesn't seem that such a module does exist - would it be technically possible to write this module for D6?
