Understanding Name Server Statistics
You should periodically
look over the statistics on some
of your name servers. Name server statistics are viewed with the
System Monitor. To start it, select Start
→
Administrative Tools
→
Performance. Make sure System Monitor is selected in the left pane,
right-click in the right pane, and select Add
Counters. Select DNS in
the Performance object pull-down
list. You’ll see a list of all the server parameters
that you can monitor in real time. A brief explanation of each
parameter is available in the Windows online help system document
entitled “Monitoring DNS server
performance.” To view this document, choose
Start
→
Help and type
Monitoring
DNS
Server
Performance
in
the search box and press Enter.
Click the help topic button in the left pane and click on the
document link when it appears.
Selecting all parameters is not useful—it produces too much information. To get an idea of the amount of memory being used by the server, choose Caching Memory and Database Node Memory. To see how busy the server is—that is, how many queries it is handling—look at Total Query Received/sec and Total Response Sent/sec. To select several parameters, hold down the Ctrl key while single-clicking. When you’ve selected all the ones you want, choose Add, then Close. Note that you have to save this list if you want to avoid selecting the list of parameters again. Select File → Save As to produce a .msc file that you can use for subsequent monitoring sessions.
