I was running a graylog version 3.3 server and I decided to upgrade to latest version 4, everything seems to be working fine appart from the jmx metrics which I am using. From the ui it seems that the metrics are available, however via jmx they are not showing. Does anyone have an idea what might be the issue ? Nothing has been changed apart from the graylog version and I am not seeing any issues related to this topic for this particular version.
It seems that in the new graylog the metrics have changed their name and that’s why they were not working. If someone has similar issue the easiest way to fix it is to verify the names via the jconsole and update it accordingly.
