User Interfaces

In WS, there are presently two ways in which you can access the service data aggregated by the Index Service:  the GT3.2 Service Data Browser and the ogsi-find-service-data command.

GT3.2 Service Data Browser

The Service Data Browser is the GUI to service data within GT3.  The Browser allows you to view the details of the Grid services available to you from a Registry configured by your administrator.  These services include, but are not limited to, the Index Service.  Service data can be viewed in various formats, depending on your requirements.  Refer to GT3 Service Data Browser Quick Start for details on and examples of using the Browser.

ogsi-find-service-data Command

The ogsi-find-service-data command provides a command-line interface for querying the service data available to you from the Index Service or any Grid service.

The ogsi-find-service-data command allows you to perform the following types of queries:

• By specifying a Grid service and one or more Service Data Element names.
• By specifying an XPath expression in addition to the above.

You can specify the ogsi-find-service-data command output as raw XML or as an easy-to-read outline format.

Refer to Querying Service Data for details on and examples of using the ogsi-find-service-data command.
