Information about how to configure existing aggregator sources (such as the aggregator sources distributed with the Globus Toolkit, which include one that polls for resource property information, one that collects resource property information through subscription/notification, and one that collects information by executing an executable program) is found in Aggregator Sources Reference; information about how to create new aggregator sources can be found in Developer's Guide.

The administrator of a Globus installation configures the set of available executable programs that are available to be used as action scripts (for example, an executable program may send mail to an end-user or write a structured log file that will later be read by some other program).
