The WebLogic Diagnostics Framework (WLDF) gives administrators and IT managers the ability to analyze their server operating environment using a set of components that generate information from WebLogic servers and the resources, including applications, deployed on the servers. The resulting data can then be gathered for analysis, and later persisted for long-term storage. This information (usually generated by MBeans) can be used to diagnose and resolve issues, monitor and maintain a history of events, carry out performance tuning, and perform many other useful tasks for a system administrator.
