"CA APM Manager for CA SSO (CA Wily Manager for - MULTI-PLATFORM)" is the new product name
The Download Center page for the product has "CA APM Manager for CA SSO Documentation r12.0.4.0" (GEN04150154E.zip) which gives CAWilySiteMinderManager_12.0.4.0_Documentation.pdf where Appendix A discusses the metrics. Uploaded here as well.
Hope this helps.
