Error: Index gl-events

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.

at [graylog.jar:?]
at [?:1.8.0_212]

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!!!



i have installed in the same server, elasticsearch and mongodb

he @spguida

the problems are not really connected to each other. do you have more than one Graylog speaking to this elasticseach? did you have created your own index set?

Did you started with a clean elastic search?

it’s a clean installation. it’s just one graylog, and in the same server, i have installed mongodb and elasticsearch.

From one day to other, the service stop working, i hadn’t another graylog speaking with this elastic

and i never created an index, just default index.

what do you mean with that the problem are not really connected to each other? what do you think that it is?

thanks to respond!
