Thanks in advance for your help. While I was trying to reload old logs, I deleted the existing indexes:
DELETE filebeat-* DELETE graylog*
In addition deleted the filebeat data folder which had the regisry and meta.json that kept the logs processed. Then I restarted filebeat, elasticsearch, logstash. Looking into the indexes I am able to find the following:
log1 logstash]$ curl 'localhost:9200/_cat/indices?v' health status index uuid pri rep docs.count docs.deleted store.size pri.store.size green open graylog_0 G6IrO1WpR7mQfTiddFjiZQ 1 0 0 0 261b 261b green open .kibana_1 1IAWVOajR5O_CBQLANBq7Q 1 0 4 0 15.5kb 15.5kb
However, in Kibana I am not able to create index patterns:
How can I be able to create index patterns again?
Thanks a lot
