Viewing Statistics

The ProxyServer is capable of providing statistics for each port and for the whole system. These
statistics can be useful for troubleshooting and management purposes. To access this information,
click Statistics in the Proxy Setup menu. The Statistics dialog is displayed.

From this menu, you can observe total system statistics such as Total Up Time, and Total Calls. In
addition, you can view the real-time statistics of a specific port by selecting that port from the list and
clicking Details, or click Log... to save current statistics to a log file for future use (i.e.,
troubleshooting, management).
