up to NAM 2018 it was possible to fix dictionary inconsistency problems (as described in https://answers.dynatrace.com/spaces/160/open-q-a_2/questions/205303/delay-in-performance-data-proce... or similarly here: https://www.dynatrace.com/support/doc/nam/release-notes/known-issues/#anchor_KI01 ) by going to Admin console -> Commands Console -> Dictionary fix (or "dictionary clear flag".
However, in NAM 2019 there is no longer such an option, only "Dictionary check" is available.
Just wondering, are dictionary inconsistencies no longer possible? Or, if inconsistencies or other problems related to dictionary consistency should occur, how to proceed?
It is currently a fully automated process and the fix is applied without user interaction so there is no need to have this command in 2019. You could check whether there were any inconsistencies by browsing log files or Alert explorer. There should also be a note module status if such event happened.
