Some issues related to URL monitoring authentication are noticeable in the WebMonitor log file such as:
http://webaddress: ECHO ERROR [COLLECTION[0]-8] com.quest.monitoring.agent.webmonitor.collector.URLCollectionTask - Could not get the credential for the target URL: http://webaddress
The credentials though have been setup and the locks have been released to the agents.
The troubleshootings and findings have led to the facts that the URLs being accessed or monitored are using NTLM for the authentication.
NTLM authentication is not supported in the current WebMonitor release which only supports Basic Authentication, we plan to support NTLM authentication in a future release.
