A system for serving web pages manages a plurality of web servers. The system
provides
an operator with features and tools to coordinate the operation of the multiple
web servers. The system can manage traffic by directing web page requests to available
web servers and balancing the web page request service load among the multiple
servers. The system can collect data on web page requests and web server responses
to those web page requests, and provide reporting of the data as well as automatic
and manual analysis tools. The system can monitor for specific events, and can
act automatically upon the occurrence of such events. The events can include predictions
or thresholds that indicate impending system crises. The system can include crisis
management capability to provide automatic error recovery, and to guide a system
operator through the possible actions that can be taken to recover from events
such as component failure or network environment problems. The system can present
current information about the system operation to a system operator. The system
can manage content replication.
