Problem

When two or more tagIDs inside a tag group have the same name, this causes some problems with the Checkmk service. This issue can lead to notifications not working as expected. 

E.g.,

This will cause unexpected results where one of these tagIDs will be ignored in favor of the other. 

Solution


For now, the simplest solution is to modify one of the tagIDs to something unique.


  1. Go to Setup → Tags → Edit on the Tag group you are trying to modify

    SCreenshot of Tag Groups section of the UI. Highlights the location of the edit button


  2. Enter a new unique tagID to replace the one that is causing the conflict
