How to enable non-error Apache log on MAMP

I found the answer here: https://documentation.mamp.info/en/MAMP-Mac/FAQ/#where-can-i-find-the-log-files

All log files are stored in: /Applications/MAMP/logs/

The logs need to be enabled on Apache.
In the file /Applications/MAMP/conf/apache/https.conf find the lines

#CustomLog logs/access_log combined

Please uncomment this line by removing the '#', if you do it Apache will write the access logs into /Applications/MAMP/Library/logs/access_log.
It may not be what you want, if you want to get the access logs in the same directory as the others logs (/Applications/MAMP/logs/) use the absolute path to the file:

CustomLog /Applications/MAMP/logs/apache_access_log combined

combined is a log format, that you can find on a line LogFormat

About logs, please note that you can also configure the error logs and the log level.

ErrorLog "/Applications/MAMP/logs/apache_error.log"
LogLevel error

After doing this, restart your MAMP Apache server.

I had success with adding this to the "Additional parameters for <VirtualHost>"

CustomLog "/Applications/MAMP/logs/mySiteName_access.log" combined

All is explained at http://httpd.apache.org/docs/2.2/mod/mod_log_config.html Use LogFormat to define a format, CustomLog to define a location.
