Logging

GNU Radius reports every event worth mentioning. The events are segregated by their severity level. Radius discerns the following levels (in order of increasing severity):

Debug

The debug messages section Debugging.

Auth

Under this level every authentication attempt is logged. This is enabled by setting

    level auth;

in category auth statement of `config' file.

Proxy

Messages regarding proxy requests (see section Proxying).

Info

Informational messages.

Notice

Normal, but significant conditions.

Warning

Warning conditions. These mean some deviations from normal work.

Error

Error conditions. Usually these require special attention.

CRIT

Critical conditions due to which Radius is no longer able to continue working. These require urgent actions from the site administrator.

By default, all messages in all levels are output to file `radlog/radius.log'. In addition, messages in level CRIT are also duplicated to the system console. These defaults can be overridden using logging statement in `raddb/config' file (See section logging block, for the description of logging statement syntax, see section Naming Conventions for information about the locations of different radius configuration files).
