# Setting Custom Log Sizes

### What is log4net

log4net is a tool to help the programmer output log statements to a variety of output targets.

We are using it for application debugging and auditing.

### Configuration

The log4net environment is fully configurable programmatically. However, it is far more flexible to configure log4net using configuration files. Currently, configuration files are written in XML. The log4net file can be found in the TAP studio installation folder (by default, the path is C:\Program Files (x86)\TAP Studio\Tailent).

To edit the log4net file, open it with a text editor and you will be able to edit the configurations.<br>
