One of OODT's core strengths is the loosely connected nature of its components. This architecture allows data management infrastructures to be composed by linking the core building blocks together in various ways to support a broad spectrum of data system requirements.

Three of the core OODT components, the File Manager, Workflow Manager, and Resource Manager, along with components for crawling data repositories and extracting metadata, together represent the fundamental ingredients of many large-scale data system projects and are often referred to as a Process Control System or PCS. This session will discuss a new, unified "operator" interface for monitoring and interacting with the Process Control System.

The OODT PCS Operator User Interface, or OpsUI, provides high-level and detailed information about the status of the underlying components in an intuitive, browser-based interface. It takes advantage of a suite of RESTful web services developed in OODT 0.3 that expose component level information as JSON.

This session will provide an overview of the OpsUI, discuss the services it provides, and explain how the interface can be used to monitor and manage a full-scale data system in real time.
