Dear Users,
about 30 days ago, I instantiated a VM whit Ubuntu 22.04 OS, 8 cores and 16 GB RAM and I installed the Open versione of Graylog v.6.1.8.
After some basic configurations, everything started working as expected, without any issues.
Today, I discovered that, in the search window, an error message was present:
“While retrieving data for this widget, the following error(s) occurred:
Connection refused.”
In the top left of the screen, IN messages number was increasing, but OUT was 0.
So, I tried to restart datanode and server, but nothing changed.
I also restarted the OS without success. In the end, I updated Graylog from 6.1.8 to 6.1.10.
Error message disappeared, IN and OUT values were changing as expected, but no logs were visible in the search page. After about 1 hour, I restarted again the services and now I can see some logs, but they seems to be old logs.
Since I’m still a newbie, could you please help me to understand what happened and how to avoid it happen again?
Thank you,
Mauro
