Re: Tool to analyze and minimize loaded modules.

[Mike Rumph]

Hello Christian,

Excellent.  This looks very useful.
And yes.  On second thought, this topic may be more suitable for the 
user mailing list.

There are maybe many Apache users who could benefit from this.
I started it on dev because I was considering developing something on 
this if there wasn't already.

Please, feel free to present this on the user mailing list.

Thanks,

Mike

Hello Mike,

This is probably more a user-ML related question, but I have a little
script to do this in the 2nd of my Apache/ModSecurity tutorials at

-> Step 9

Cheers,

Hello all,

I was wondering is there is any tool available that can analyze the
directives in an httpd instance's configuration files and determine which
loaded module are not being used.
If not, maybe such a tool could be quite useful for reducing the memory
footprint.

Thanks,

Thanks Yehuda,

That looks like a good starting point.

The server-info handler can give you some of that information, but not

It lists each module and the relevant configuration, but mod_info

SetHandler server-info is listed in core.c and for me there is no 
configuration listed under mod_info.


I cut this down from the full config to show relevant parts.
