		6.	How many queries is the server seeing?
		7.	What types of queries is the server seeing?
		8.  What other statistics does the server generate which we can chart?

	There's two parts to this goal:

		1.  Real time "Is it up?" monitoring

		2.  Historical "How does it perform?" monitoring

	Tools like BigBrother, Spong, mon, etc... are good at #1, but not #2.

	Tools like mrtg, cricket+rrd, orca+rrd, rrdtool, etc... are good 
at #2, but not #1.

	All of these tools require some configuration and perhaps some 
script development in order to support.  If you want them to be 
queryable from the 'net, you may have to also do some work with 
Net-SNMP (or other SNMP tool), so that you can take the data 
periodically logged by BIND and make it available to programs that 
are not on the local machine.
