Figure 240 Monitor > Anti-X Statistics > Anti-Spam > Status 260 The following table describes the labels in this screen. Table 49 Monitor > Anti-X Statistics > Anti-Spam > Status LABEL DESCRIPTION Refresh Click this button to update the information displayed on this screen. Flush Click this button to clear the DNSBL statistics. This also clears the concurrent mail session scanning bar's historical high. Concurrent Mail The darker shaded part of the bar shows how much of the ZyWALL's Session Scanning total spam checking capability is currently being used. The lighter shaded part of the bar and the pop-up show the historical high. DNSBL Statistics # DNSBL Domain Total Queries Avg. Response Time (sec) No Response The first number to the right of the bar is how many e-mail sessions the ZyWALL is presently checking for spam. The second number is the maximum number of e-mail sessions that the ZyWALL can check at once. An e-mail session is when an e-mail client and e-mail server (or two e-mail servers) connect through the ZyWALL. These are the statistics for the DNSBL the ZyWALL uses. These statistics are for when the ZyWALL actually queries the DNSBL servers. Matches for DNSBL responses stored in the cache do not affect these statistics. This is the entry's index number in the list. These are the DNSBLs the ZyWALL uses to check sender and relay IP addresses in e-mails. This is the total number of DNS queries the ZyWALL has sent to this DNSBL. This is the average for how long it takes to receive a reply from this DNSBL. This is how many DNS queries the ZyWALL sent to this DNSBL without receiving a reply. ZyWALL USG 2000 User's Guide
