AXL-Serviceability APIs are based on SOAP with XML request and response messages. They must conform to the structure of a SOAP Envelope element. Although SOAP is a standard protocol, many of its data model aspects are left open for flexibility reasons. For example, it permits different transport protocols such as SMTP, FTP, or HTTP to carry SOAP messages. The implementation of a SOAP service must specify the bindings of the data model to constitute a concrete wire protocol specification.
WSDL 1.1[2] provides the mechanism to describe the complete SOAP bindings that AXL-Serviceability APIs use.
The following Cisco CallManager server file contains perfmon SOAP requests service definitions:
http://ASTSERVERNAME/soap/AstService.wsdl
The following file contains Cisco CallManager and CTI manager SOAP real-time information requests definitions:
http://ASTSERVERNAME/soap/risport.wsdl
To know what services are available, how to form the request message, and to interpret the response message properly, you must download these files. Basically, the WSDL file has everything that you need to know about AXL-Serviceability APIs. You can get the WSDL file as a static XML page.
ASTSERVERNAME refers to the server on which the AXL-Serviceability APIs is running.
