We have Graylog 2.1. and we have a lot of Indexer failures.
I have read http://docs.graylog.org/en/2.1/pages/indexer_failures.html, but there is nothing how to debug it or how to solve this problem.
I think this log is from windows servers, there is nxlog and collector sidecar.
What should I do to fix these issues?
Is it possible to use “Letter ID” in order to see message which failed to be indexed, or is there any other way to do that?
Thanks in advance,
