Today I was checking at disk usage. On my server I host only one domain. I have 3 apache access log files: /var/www/clients/client1/web1/log/20151313-access.log --> 1.4G /var/log/ispconfig/httpd/mysite.com/20151313-access.log --> 1.4G /var/log/apache2/other_vhosts_access.log --> 1.3G The first two started both at 00:00:00 and are identical in size The third one started at 06:25:14 (probably due the compression of others logs or some system maintenance service) and is a lillte smaller. Anyway can somone help me understand why do I have 3 access log files? Thank you!
