Summary

Argent Sentry Connectivity Rules using TCP/IP Ping or Port Scanning does not work for URL Objects in Argent Sentry due to error ‘Could not resolve host XXXX by DNS‘

Technical Background

When URL Object is defined in CMDB-X, the URL address is saved as Alias field in node property

When Engine runs TCP related Connectivity Rule, it looks for alternative IP address and it is not defined

As a result, Engine tries to resolve URL Object name through DNS, which does not work either

Resolution

Upgrade to Argent Advanced Technology 3.1A-1401-T4 or later

If Customer cannot upgrade immediately, they need to manually specify the alternative IP address in the CMDB-X node property for the URL Object
