# Set Web Service Context

Overview Configuration

## Overview
The Set Web Service Context filter is used in a policy to determine the service to obtain resources from in the Web Service Repository. For example, by pointing this filter at a pre-configured `getQuote` service in the Web Service Repository, the policy knows to return the WSDL for this particular service when a WSDL request is received. The Return WSDL filter is used in conjunction with this filter to achieve this. The Set Web Service Context filter is configured automatically when auto-generating a policy from a WSDL file and is not normally manually configured. For a detailed example, see the Web Services Repository tutorial.
## Configuration
Name: Enter a name for the filter in the Name: field. Service WSDL: Select a service definition (WSDL file) from the Web Service Repository by selecting the checkbox for the desired service. For more details on adding services to the Web Services Repository, see the Web Services Repository tutorial. Monitoring: The fields on this tab enable you to configure whether this Web Service stores usage metrics data to a database. This information can be used by Service Monitor to produce reports showing how and who is calling this Web Service. The following fields are available on this tab: Monitor service usage: Select this option if you want to store message metrics for this Web Service. Monitor service usage per client: Select this option if you want to generate reports monitoring which authenticated clients are calling which Web Services. Monitor client usage: If you want to generate reports on authenticated clients, but are not interested in what Web Services they are calling, select this option and unselect the Monitoring service usage per client checkbox. Which attribute is used to identify the client?: Enter the message attribute to use to identify authenticated clients. The default is `authentication.subject.id`, which stores the identifier of the authenticated user (for example, the username or user's X.509 Distinguished Name).
