All kind of log (Apache) files that lost in linux space

This is not day by day working problem but rather one occasionally come surfacing and the encounter is always made solving harder. Why? because my memory become less and less limited..

So here it is, the great Apache in a web server forms and its all kind of written actions here and there lies in LOG FILES.
Where is the LOG FILES? Oh my.. I dont remember where the heck that is

Thanks to some useful sites and I'll backed it up here in case of long this become forgotten and I still can find some hazy trace of solutions.

How to find logfiles in Linux:
locate httpd.conf --> $root_dir\find . -name "httpd.conf"
grep line containing file information --> grep "ErrorLog" [httpd.conf location]

Now its sight of relieve....
