The SLF4J stuff you can ignore. The exception is from when it tries to load /etc/maddash/maddash-server/maddash.yaml. The stack trace is complaining that the “grids” property in that file is a string. Sounds like maybe your psconfig-maddash-agent hasn’t run yet to fill in that file?

Thanks,
Andy

Background: everything we had setup for a central dashboard broke when the auto-upgrade to version 5 happened last April. I thought I'd be clever and bring up the base OS to something that wasn't being deprecated in the next year while I was messing with it (namely Alma 9). I think I have several issues, but I'll start with one I can clearly articulate...

When I run 'systemctl restart maddash-server', it looks happy for several seconds and then fails.

/var/log/maddash/maddash-server.out reveals many 'JarClassLoader' warnings - I'm guessing those are advisory only. I have 365 lines of those.

Those are followed by these lines:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
MLog initialization issue: slf4j found no binding or threatened to use its (dangerously silent) NOPLogger. We consider the slf4j library not found.
Initialization error: java.lang.String cannot be cast to java.util.Map
java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Map

Looking for files containing 'slf4j; reveals files in
- /usr/share/logstash/logstash-core/lib/jars
- /usr/share/logstash/vendor/bundle/jruby/2.5.0/gems
- /usr/share/opensearch/plugins/opensearch-*

Any clues on how to get this piece running?
