Error in graylog

Graylog Central (peer support)

Hi Team, we were full of our disk space, hence we deleted few indexes, using the below command:
curl -XDELETE http://localhost:9200/graylog_9

now after restarting graylog, it is giving us the below error:

While retrieving data for this widget, the following error(s) occurred:

  • Elasticsearch exception [type=index_not_found_exception, reason=no such index [graylog_9]].

Could someone please help me to solve this issue?

Thanks,
Abhishek

Hello && Welcome

So, it looks like the index you deleted had data for that widget, which no longer exists.
Try remaking that widget, also did you rotate your indices after deleting them? Just a note it’s kind of bad deleting index using CLI, I understand you probably had no choice, I’ve been there. You might want to reduce your log retention and/or add space if you haven’t already.
