Better late than never…
Having set many Host Tags (listed under Custom Attributes) within several hosts and rulesets based on these tags in Checkmk v2.0… I am so glad to hear that there is no impact or changes in v2.2.
However, when I do import Hosts via CSV (WATO) with these tag’s values, it fails to import the tags that were already created. Is the feature still available or tags are no longer accepted when importing in v2.0?
