CA Application Performance Management Agent (APM / Wily / Introscope) INTROSCOPE


I am trying to install and enable Introscope agent to monitor Apache web server. Getting below errors, in IntroscopeAgent.log. 5/16/19 10:44:05 AM EDT [ERROR] [IntroscopeAgent.WebserverMonitor.WebServerMonitorEngine] Could not get metrics from server : https://mqlwebs001:57003 PKIX path building failed: unable to find valid certification path to requested target at at at at at at at at at at at at at at


Self-signed certificate in non-permissive mode.


Component: APMISP


In the permissive mode, the CA APM for Web Servers acts as a permissive client that accepts all kinds of web server certificates. These certificates include unsigned, self-signed, trusted, and expired certificates. In the non-permissive mode, the CA APM for Web Servers accepts only unexpired and trusted certificates.     
Customer was using a self-signed cert and needed permissive mode. Once changing. the errors went away and metrics appeared.
