I use Graylog 2.4.6 (I will update it to 2.5.1 soon).
I got this error message but I solved it. The problem My graylog was not connected for 14 days and I did not know it.
Where is this type of message stored on the server? where are the logs of the system graylog located?
Or how can I do to be warned quickly if notifications like this happens again ?
For notification errors such as “Journal Utilization is too high” or “Uncommited messages deleted from journal”
