I'm here because after having developped and clear all my grok filter on logstash, to have something very clear .. I've done a :
curl -XDELETE 'localhost:9200/_all'
Then a lot of errors appeared and I've decided to just delete my logstash-* index to create it again and just keep my final attributs.
The problem is now, I can't create my logstash-* index anymore with the time-based options, and I don't understand why.
I've check all my conf files and they seems ok and havn't change
