The DSDL provides convenience functions to return network address information for resources and resource groups. For example, the scds_get_netaddr_list() retrieves the network address resources that are used by a resource, enabling a fault monitor to probe the application.
The DSDL also provides a set of functions for TCP-based monitoring. Typically, these functions establish a simple socket connect to a service, read and write data to the service, and disconnect from the service. The result of the probe can be sent to the DSDL scds_fm_action() function to determine the action to take.
See xfnts_validate Method for an example of TCP-based fault monitoring.
