Service Groups show both mandatory "Servicegroup" and optional "Display Name"

[thomas-merz]

Describe the bug

"Service Groups" shows "Name/Servicegroup" and "Display Name" instead of only one of them as in the past.

Expected behavior

"Service Groups" should only show "Name/Servicegroup" if "Display Name" is empty instead of showing both all the time.

@dgoetz , FYI!? This seems to have started after we migrated IcingaDB… 🤷🏼‍♂️

[dgoetz]

Request makes totally sense for me as you would set a display name to have it displayed instead, not in addition. And with Icinga 2 being able to use any characters in object names I do not see a use in having a display name instead of the name at all.
But the issue should be moved to https://github.com/Icinga/icingadb-web/issues what someone from the Icinga project should be able to do.

[slalomsk8er]

@dgoetz The sense in having object names and display names is as follows:
If you rename a object you loose the connection to the history in the time series database but if you change the display name the connection stays.

[thomas-merz]

@slalomsk8er , that's a nice explanation. But nevertheless is seems pretty useless or at least very redundant to show BOTH. One ("Display Name") should be enough 😄

[dgoetz]

@slalomsk8er Yes, but not for groups (or at least not in the default scenario and most others). And as @thomas-merz says those use cases are not related to displaying both. For hosts I would also say showing both optionally like it is done has its use cases as I have seen environments where the display name of a host was more descriptive while the object name was the real host name, but we are here talking just about groups.

[slalomsk8er]

True, for groups it doesn't matter.

[slalomsk8er]

Maybe having both does also matter for groups as renaming via display name will preserve links.
But showing both makes no sense to me.
