Environment

DX NetOps 21.2 Spectrum / DX Netops Performance Management integration

Cause

The faultString: (401)Unauthorized client error on Spectrum OneClick server indicates that the request to DX Netops Performance Management has not been accepted because it lacks valid authentication to the Netops Portal server.

Issue is likely that the certificate for SSO is configured with the Fully Qualified Domain Name (FQDN).  However, if the system is setup to use short hostnames, then DM/EM is accessing SSO using the short hostname and shows errors relating to subject alternate name issue.  So it cannot instantiate the bean it uses to identify the hostname, hence, it is blank.

 

Resolution

Change Web Service Host (NpcWebServiceHost) to FQHN in both /opt/CA/PerformanceCenter/SsoConfig and ~/etc/Hosts locally.

After some syncs/etc, Spectrum should start seeing events from Device Manager (DM) / Event Manager (EM) on the Netops Portal server.
