Database dump and statistics tools can help you review and manage
server performance.
Domain Name System (DNS) provides several diagnostic tools. They can be
used to monitor performance of your server.
Server statistics
The server statistics summarize the number of queries and responses the server received since the last time the server restarted or reloaded its database.
Active server database
The active server database contains zone and host information, including some zone properties, such as start of authority (SOA) information, and through host properties, such as mail exchanger (MX) information, which might be useful in tracking down problems.
