Once you have enabled statistics, you can get a variety of information on how your server instance is running. The statistics are broken up into functional areas.
This section describes how a subset of the proxystats.xml data can be viewed in the Server Manager.
You can view totals, maximum values, peak numbers, and bar graphs of information pertaining to connections to the Proxy Server, DNS processing, keep-alive values, cache, and server requests.
The following section describe the types of information that may be obtained for each of these areas.
The following connection statistics are available from the Server Manager:
Total number of connections
Maximum number of queued connections
Peak number of queued connections
Current number of queued connections
Number of processes
The following DNS statistics are available from the Server Manager:

Number of processes
Number of DNS cache hits (also shown as a bar graph)
Number of DNS cache misses (also shown as a bar graph)

Maximum keep-alive connections
Keep-alive timeout
Number of processes
Number of keep-alive hits (also shown as a bar graph)
Number of keep-alive flushes (also shown as a bar graph)

Click Submit.
If your server instance is running, and you have enabled Statistics/Profiling, you see a page displaying the kind of statistics you selected. The page is updated every 5-15 seconds, depending upon the value of the refresh interval.
Select the process ID from the drop-down list.
You can view current activity through the Server Manager, but these categories are not fully relevant for tuning your server. The perfdump statistics are recommended for tuning your server. For more information, see the next section.
