Logging

From BaseX Documentation

Jump to: navigation, search

This article is part of the Advanced User's Guide. It describes how client operations are logged by the server. The server logs can e.g. be used to get an overview of all processes executed on your server, trace any errors or compile performance statistics.

The server logs are written in plain text. In your Database Directory, you can find a folder named .logs in which all log files are stored with the according date. Note that, depending on your OS and configuration, files and folders beinning with a . may be hidden. The log directory can be changed via the LOGPATH option.

Some more notes on the logging facility:
