Detailed log entries are produced for every page access in the
/logfolder of the project.
In a Docker environment, the log can be viewed from outside the container as follows:
docker logs CONTAINER-NAME --follow
Log entries show how the server side PHP code for the page request is traversed. Also, SQL statements are logged and errors are reported. For debugging purposes, or to see what a user has done when something doesn't work as expected, the log file is a great resource.
DRDB checks the log file size and archives the file into a .tar.gz file once its size exceeds 10 MB.
PHP and Apache Error Logs
- PHP and Apache error logs are recorded in
text /var/log/apache2/error.log. In a Docker environment, they are also forwarded to the default log output and will be shown together with the DRDB logs with the
docker logs...command above.
