The logging tab shows the various log files that Duplicator generates. There are currently two types of log files, the first is the trace log which is only available in Pro. The second is the package log which is available in both Pro and Lite.
Below is a synopsis for each file:
- Trace Log: Pro The trace log file records all information that is going on at all times with the plugin. Since multiple requests can be executed by multiple users, the trace log takes all communication from the plugin into consideration and logs that data. To further improve the full picture of all activity going on in PHP on the server (not just Duplicator Pro), you can turn on Enhanced trace logging in Settings > General > Debug. This option will also log all trace log activity to the PHP error log.
- Package Log: The package log is a log file that is generated for every package that is built. The log will show the progress and state of the package. It will also display most errors/warnings that may happen during the creation of a package file.
The default log selected will be the trace log in Pro. In Lite, it will be the last package log. There are currently two trace log files stored in your default store location. The active trace log and a running backup log which will be labeled *.log1. The running backup will be created once your primary trace log starts to get too large.
Each log file is represented as a link. Click on the link name and the log will be visible in the output window. To update the log, click the refresh button or have it autorefresh every 10 seconds by enabling the Auto Refresh option.
