Issue/Introduction

When attempting to access the following URL:http://DA:8581/dcdebug/,

It redirects unexpectedly to:https://DA:8382/sso/sign-in.jsp?SsoProductCode

This redirection leads to an error.

However, the URL http://DA:8581/rest/ works as expected.

When accessing http://DA:8581/dcdebug/ using a REST client, the following error occurs:

java.net.UnknownHostException: DA
     at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
     at java.net.InetAddress$2.lookupAllHostAddr(InetAddress.java:929)
     at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1324

Environment

DX NetOps Performance Management Release : 22.2 or later

Cause

The issue is caused by the use of a non-Fully Qualified Domain Name (FQDN) —Data aggregator — which is not resolvable in some environments. This leads to SSO redirection failures and name resolution errors.

Resolution

Update the hostname for the Data Aggregator (DA) to use its Fully Qualified Domain Name (FQDN) in the NetOps Portal:

Navigate to Administration > Data Sources in the NetOps Portal.

Locate and edit the entry for the Data Aggregator.

Replace the short hostname (e.g., DA) with its FQDN (e.g., da.example.com).

Save the changes.

Additional Information

FQDNs ensure consistent name resolution across systems, preventing issues like UnknownHostException.

This change also helps maintain proper integration and authentication flows between NetOps Portal and Data Aggregator.
