Abstract: This invention relates to managing multiple web servers, and more particularly to a web service system and method that allows a system operator to distribute content to each web server in the web service system. In one embodiment, a method for replicating changes in a source file set on a destination file system includes identifying changes in a source file set, storing the identified changes in a modification list, and transmitting the modification list to an agent having access to a destination file system. In another embodiment, a method for replicating changes in a source file set on a destination file system includes identifying changes in a source file set, storing the identified changes in a modification list, and transmitting the modification list to a plurality of web servers.

Abstract: 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 may 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 may 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 may monitor for specific events, and may act automatically upon the occurrence of such events. The events may include predictions or thresholds that indicate impending system crises. The system may 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.

Abstract: Changes to files in a master source file set on a master computer are identified. Local host addresses of the files are converted to uniform resource locators. The identified changes are stored in a modification list comprising the uniform resource locators specifying changed files of the master source file set. The modification list is transmitted to one or more computers, notifying the one or more computers that the master source file set has changed. A response is received from at least one of the one or more computers, indicating that the identified changes are installed. An alert is issued indicating that a copying of the changes by an agent in at least one of the one or more computers has failed, to cause a traffic manager that redirects traffic to decrease requests made to a web server on the computer having the agent.

Abstract: Records written to each of a number of logs, such as logs in a distributed processing system, are monitored. An index to records in the logs is generated according to the monitoring of the records. The writing of records to each of the logs is performed by a corresponding task, and the monitoring and generating are performed by one or more tasks that are separate from the tasks performing the writing of the records. When log records are removed, updating of the index can be deferred or performed according to a schedule such that the index does not reflect the removal of the log records.

Abstract: Described are techniques used with application monitoring in connection with performing Web Services. Associated with each application performing a service are one or more application servers and associated stream sensors. The stream sensors filter received XML messages in accordance with a set of rules to gather data. The filtered data is gathered at each point and then may be aggregated locally for each transaction by an aggregation service. Data may be gathered from each aggregation service by a global aggregator. Rules are specified initially and may be revised during runtime while gathering data. Rules are evaluated at runtime in accordance with the data stream.

Abstract: This invention relates to managing multiple web servers, and more particularly to a web service system and method that allows a system operator to distribute content to each web server in the web service system and notifying a computer, such as a cache server, of content changes. In one embodiment, a method for notifying a computer of changed files includes identifying changes in a source file set, storing the identified changes in a modification list comprising uniform resource locators specifying the changed files, and transmitting the modification list to a computer. In another embodiment, a method for replicating changes in a source file set on a destination file system and for notifying a computer of the changes includes identifying changes in a source file set, storing the changes in a first modification list, and transmitting the first modification list to an agent having access to a destination file system.
