10.2 Debugging

GNU Radius provides extensive debugging features. These are enabled either by the `--debug' (`-x') command line option to radiusd (see section 4. How to Start the Daemon.), or by the level statement in the debug category (see section logging statement). Both cases require as an argument a valid debug specification.

A debug specification sets the module for which the debugging should be enabled and the debugging level. The higher the level is, the more detailed information is provided. The module name and level are separated by an equal sign. If the level is omitted, the highest possible level (100) is assumed. The module name may be abbreviated to the first N characters, in which case the first matching module is selected. Several such specifications can be specified, in which case they should be separated by commas. For example, the following is a valid debug specification:

proxy.c=10,files.c,config.y=1

It sets debug level 10 for module proxy.c, 100 for files.c, and 1 for config.y.

The modules and debugging levels are subject to change from release to release.
