How is the CMDB CI related list "DNS Names for CIs" used? Or the Alias table?

[tsutherland]

We have servers with multiple aliases in DNS (server1 is the hostname, and there are alias1, alias2, alias3). Logic would tell me that in discovery (or some other method) the alias names would appear in either the DNS Names for CIs related list of the server or that the alias names would be in the alias table. Neither of these things is true in our environment and so I am wondering if we need to manually build those relationships or if there is a special probe or something that we need to employ.

End use case is that we want to be able to let end users use the alias instead of the real server name using a method similar to this. In most cases, there are several aliases for a single server so a custom field on the CI won't work and I'm hoping we can use the alias table or a related list.

Any ideas would be most welcome!

Did you ever happen to get this figured out? I have just started looking into this for my network team and would appreciate any advice you may have found out.

Thanks

I ended up opening a HI case and this was the end result: 

As per our zoom session, we are able to get the DNS name for the CI and OOB we do not populate DNS alias information for the windows servers and we do populate that for AWS and Azure cloud discovery.

Please go ahead and submit an idea in the idea portal so that we can have our Product team check the request and decide on implementing this for future releases.

So, basically that feature is useless for us.... 😉  But I did submit an idea here if you'd like to upvote it.

Thanks for responding. I have up voted your idea!
