The Web application Server features session tracking (that is, tracking user requests). Use the session tracing page of manager to configure session tracking. The session tracker merges several related requests from the same user into a single session (that is, a HttpSession object). A session tracker can also enable multiple instances of a Web application server to share a common buffer pool of sessions (t

much each service contributes to the total delay. With distributed tracking, we have better visibility of the situation.

whole storage system. A group can consist of one or more storage servers, and the files in a storage server under a group are the same, and multiple storage servers in group play a role of redundant backup and load balancing (one group has storage capacity of the smallest storage server in the group. Different groups of storage servers do not communicate with each other, and storage servers within the same group are connected to each other for file synchronization. When adding servers to the gr

Integration with Bug Tracking System/problem tracking In software development, modification depends on a bug or problem number. Users of the Bug Tracking System (problem tracker) like to associate the modification of the subversion with a specified number in the problem tracking. Therefore, many problem trackers provide a pre-submitted hook script to analyze logs and find the submitted bug numbers. This is slightly less reliable, because it relies o
