Thanks to Ivan Garnizov for helping me get through this! My problem stemmed from an invalid limits.conf (which I inherited, so I'm not sure how it was working before?)

I'm still not getting anything on my dashboard, but I'm back to actually running tests, so it's something I can dig into. I'll let you know if I have any further issues.

Now that people are back from winter breaks and the list is getting active again, could somebody advise me on this?

All right, I think I've got the next issue distilled to something I can ask about.

I've created a JSON file on my central server. Here's the section generated by psconfig:
==
 "archives" : {
    "archiver": "http",
    "data": {
        "schema": 3,
        "_url": "https://ps-dashboard5.perfsonar.kanren.net/logstash",
        "verify-ssl": false,
        "op": "put",
        "_headers": {
            "x-ps-observer": "{% scheduled_by_address %}",
            "content-type": "application/json"
        }
    },
    "_meta": {
        "esmond_url": "https://ps-dashboard5.perfsonar.kanren.net/esmond/perfsonar/archive/"
    }
   },
==
If you want the full JSON file, https://ps-dashboard5.perfsonar.kanren.net/toolkit/KanREN.json
I've used 'psconfig remote add' on my measurement hosts. One example:
==
$ psconfig remote list
=== pScheduler Agent ===
[
   {
      "url" : "http://dashboard.greatplains.net/psconfig/gpn_psconfig.json",
      "configure-archives" : true
   },
   {
      "url" : "https://ps-dashboard5.perfsonar.kanren.net/toolkit/KanREN.json",
      "configure-archives" : true
   }
]
==

However, I am not seeing any hits in my apache logs for either anything containing "logstash" nor for anything containing "esmond"

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.

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?
