Hi John,
Introscope Webservices documentation is available from here:CA Introscope Web Services API Reference - CA Application Performance Management - 10.2 - CA Technologies Documentation
Here is an phyton example how query Introscope PollingWebServicePythonCode.py
Another example is here apmmodel_sampleclient.zip
Also, I see from the old Wily Software download site, that in previous releases we used to make available a sample app and additional documentation on tips and best practices, if you are interested, open a case and request for download link for Introscope Introscope Integration Software Developer Kit (SDK):
Packages
-IntroscopeWsSDKWebapp.zip SDK Web Application
-IntroscopeWsSDKSampleEclipseProject.tar Sample Eclipse Project
-IntroscopeWsSDKSampleEclipseProject.zip Sample Eclipse Project
..
-IntroscopeIntegrationSDKDocs.zip Documentation (Zip Format)
..
I hope this helps,
Sergio
