Robert,
I am not sure what you have found in our documentaion or not but in the 3.2 CAPAM documentation, here are the urls that will bring you directly to the Threat Analytics install information:
Deploy CA Threat Analytics Server
https://docops.ca.com/ca-privileged-access-manager/3-2/EN/integrating/integrate-with-ca-threat-analytics/deploy-ca-threat-analytics-server
Install CA Threat Analytics Server into a Virtual Environment
https://docops.ca.com/ca-privileged-access-manager/3-2/EN/integrating/integrate-with-ca-threat-analytics/deploy-ca-threat-analytics-server#DeployCAThreatAnalyticsServer-InstallCAThreatAnalyticsServerintoaVirtualEnvironment
Configure CA Threat Analytics
https://docops.ca.com/ca-privileged-access-manager/3-2/EN/integrating/integrate-with-ca-threat-analytics/deploy-ca-threat-analytics-server#DeployCAThreatAnalyticsServer-ConfigureCAThreatAnalytics
In addition, i found some articles in the Knowledge Base:
KB000109280 ca-threat-analytics-alert-configuration
KB000100056 pam-tap-integration-troubleshooting
KB000101576 how-to-deploy-ca-threat-analytics-for-pam-on-aws
KB000010785 Threat-Analysis-Insight-menu-with-500-error
Let me know if this helps you find what you are looking for.
