# Logging

```

mightyBrowser uses [Apache log4net](<https://logging.apache.org/log4net/>) as core logging library, and additionally [PostSharp Diagnostics](<http://doc.postsharp.net/5.0/logging>) for extended Debug logging.

By default, all the logs are stored in a logfile located in *'C:\\Users\\\{USER}\\AppData\\Local\\coolOrange\\mightyBrowser\\Logs\\mightyBrowser.log'* and it contains only Infos, Warnings and Errors.

The log4net settings file is located in *C:\\ProgramData\\Autodesk\\ApplicationPlugins\\coolOrange_mightyBrowser.bundle\\Contents\\mightyBrowser.log4net*.\
Further information about log4Net Configurations can be found [here](<https://logging.apache.org/log4net/release/manual/configuration.html>).

## When to change the logging behavior?

When you have issues or when you want to get a more detailed knowledge about what went wrong, you can increase the [](</logging/log_level>).

:::{note}
When changing the loglevel to *DEBUG* [PostSharp Diagnostics](<http://doc.postsharp.net/5.0/logging>) will be enabled and will log all the function calls into the log files. This could cause performance issues
:::

## LogFile

You can see, that there is just one logging-Appender, thats the *FileAppender*:

```xml
<appender name="FileAppender" type="log4net.Appender.RollingFileAppender">
```

If you want to change the [](</logging/log_level>) for the logfile, please visit in the configuartion file in the lines:

```xml
<root>
        <level value="WARN" />
        <appender-ref ref="FileAppender"/>
</root>
```

In that root element, you can configure the logginglevel for all appenders. You could set the level to "DEBUG", than all the appenders will log in debug.\
In the line

```xml
<param name="File" value="${LOCALAPPDATA}\coolOrange\mightyBrowser\Logs\mightyBrowser.log" />
```

you can configure the outputpath and name of the logfile.
