GT 4.0 WS MDS Aggregator Framework: User's Guide

1. Introduction

This component does not generally have end-users.

The WS MDS Aggregator Framework is the software framework on which WS MDS services (currently, the WS MDS Index and WS MDS Trigger services) are built. The aggregator framework collects data from an aggregator source and sends that data to an aggregator sink for processing. Aggregator sources distributed with the Globus Toolkit include modules that query service data, acquire data through subscription/notification, and execute programs to generate data. Aggregator sinks include modules that implement the WS MDS Index service interface and the WS MDS Trigger service interface.

In general, end-users will not interact directly with the aggregator framework; instead, they will interact with clients specific to the aggregator sources and aggregator sinks.

2. Command-line tools

See Aggregator Command Reference for details.

3. Graphical user interfaces

There is no GUI specifically for the aggregator framework. The release contains WebMDS which can be used to display monitoring information in a web browser. Specifically, it can be directed at services based on the aggregator framework to display information about resources registered to the aggregator framework.

4.  Troubleshooting

End-users do not generally interact directly with the aggregator framework.

General troubleshooting information can be found in the GT 4.0 Java WS Core User's Guide.
