NAMED - diagnostic options

All activities of NAMED are logged in debug mode. You can enable this mode by setting the environment variable DEBUGNAMED or via the rndc tool. The volume of diagnostic information depends on the debug level. The higher the level, the more detailed the messages. You can transfer the level directly in the environment variable DEBUGNAMED or set it with the rndc tool. You can also disable debug mode with the rndc tool.

A further diagnostic option is provided by the database dump. You can use the rndc tool to have the data in the cache and the root data output to file. You can also enable query logging with the rndc tool.

The rndc tool is described in the “BIND9 Administrator Reference Manual” of the Internet Software Consortium.
