• Overview of the WebLogic Diagnostics FrameworkWLDF consists of the following:Data creators (data publishers and data providers that are distributed across WLDF components)Data collectors (the Logger and the Harvester components)Archive componentAccessor componentInstrumentation componentWatch and Notification componentImage Capture componentMonitoring DashboardData creators generate diagnostic data that is consumed by the Logger and the Harvester. Those components coordinate with the Archive to persist the data, and they coordinate with the Watch and Notification subsystem to provide automated monitoring. The Accessor interacts with the Logger and the Harvester to expose current diagnostic data and with the Archive to present historical data. The Image Capture facility provides the means for capturing a diagnostic snapshot of a key server state. The relationship among these components is shown in Figure 2-1.Figure 2-1 Major WLDF ComponentsDescription of "Figure 2-1 Major WLDF Components"All of the framework components operate at the server level and are only aware of server scope. All the components exist entirely within the server process and participate in the standard server lifecycle. All artifacts of the framework are configured and stored on a per server basis.
