I just stumbled across a strange behaviour of Kibana (7.3.1) regarding the usage of index patterns.
I have a dashboard which contains some TSVB visualizations and „normal“ visualizations like a data table for example. All visualizations rely on the same index-pattern (e.g metricbeat-*). (This was at least my assumption.)
Once the dashboard was only showing data on the TSVB visualizations but not in the data table. There an error message was shown complaining a missing metricbeat-* index pattern.
After checking the index-patterns I saw the metricbeat-* was indeed not existing. But how could the TSVB visualizations still show data although they had metricbeat-* index pattern set in the related panel options.
It seems the TSVB visualizations are not using already existing index-patterns. They seem to use their own given index-pattern instead.
Why has this been implemented in TSVB in such a different and confusing way in compare to the other visualization types?
