server.

Traffic statistics for traffic between clients and web servers

The statistics for this section are for traffic that did not go to the cache server. Generally, statistics in this section

accumulate when the cache server is not available. When the cache server is not available, the ServerIron ADX

sends client requests directly to the network or Internet for servicing by the web servers.

Connection The total number of connections that ServerIron ADX has sent directly to

web servers.

Client->Web-Server The total number of packets and octets from clients that the ServerIron

ADX has sent directly to the web servers.
