I am following the below guide:
and everything checks out fine. When I run systemctl start opennms it seems to start fine, and I can monitor the status for about a minute before it stops.
Initial check of logs seems to point towards an issue with the Jetty server, and presumably an issue with Java, though I don’t have enough experience yet with the backend of Linux, or OpenNMS and its interactions with Java to understand the issue or how to solve it.
Any help would be greatly appreciated, this is our corporate monitoring system for our divisions and we would really like to update it.
