Hi to everyone,
i have installed:
Graylog Version 3.1.0+aa5175e, codename Quantum Dog
it’s a lab, that it doesn’t get out to internet.
yesterday, when i was to check some logs, i couldn’t see any log since 1 day a go. But, logs still arrive to graylog, because in the last 10 hours, i can see activity. after a day, i still see activiy but, with 10 hours differents.
It’s a little strange, because when i went to check the logs from graylog server, i found this:
ERROR [ConfigurationManagementPeriodical] Error while running migration <V20190705071400_AddEventIndexSetsMigration{2019-07-05T07:14:00Z}>
java.lang.IllegalStateException: Index prefix conflict: a non-events index-set with prefix already exists. Configure a different <default_events_index_prefix> value in the server config file.

I was doing some troubleshooting and i found this link, that appear has a possible solution.
but, in the link does mention to modified 2 files, one is the principal server.conf (i could modify this file)
but the other one i couldn’t found it.
Any one knows where is that file?
any one knows how to resolve this problem? because i couldn’t find too much information.
thanks a lot!!!
regards!
UPDATE:
i have installed in the same server, elasticsearch and mongodb
