In my demo installation (instance "sandkasten") I found the file 
"/etc/koha/sites/sandkasten/log4perl.conf" with the following content. 
Of course you will have to replace "sandkasten" with the name of your 
own instance.

log4perl.logger.intranet = WARN, INTRANET
log4perl.appender.INTRANET=Log::Log4perl::Appender::File
log4perl.appender.INTRANET.filename=/var/log/koha/sandkasten/intranet-error.log
log4perl.appender.INTRANET.mode=append
log4perl.appender.INTRANET.layout=PatternLayout
log4perl.appender.INTRANET.layout.ConversionPattern=[%d] [%p] %m %l %n

log4perl.logger.opac = WARN, OPAC
log4perl.appender.OPAC=Log::Log4perl::Appender::File
log4perl.appender.OPAC.filename=/var/log/koha/sandkasten/opac-error.log
log4perl.appender.OPAC.mode=append
log4perl.appender.OPAC.layout=PatternLayout
log4perl.appender.OPAC.layout.ConversionPattern=[%d] [%p] %m %l %n

The permissions are as follows:

# ls -al  /etc/koha/sites/sandkasten/log4perl.conf
-rw-r----- 1 root sandkasten-koha 643 Nov 30  2016 
/etc/koha/sites/sandkasten/log4perl.conf

I never heard about this file before so I'm quite sure it is usually 
automatically created during the creation of the instance.

However, my file "/etc/koha/sites/sandkasten/koha-conf.xml" does contain 
the following line which I never had to insert or change manually:

<log4perl_conf>/etc/koha/sites/sandkasten/log4perl.conf</log4perl_conf>

Hope this helps.

Best wishes: Michael
