We are wanting to tweak the logging levels of our Solr 7.4 nodes to see what might be helpful to add to the solr.log for debugging purposes.
In investigating what is available, however, I run /solr/admin/info/logging and I find that there is little consistency in what logging settings are available to any given node (referring here to the "name" field of the "loggers" array returned by /solr/admin/info/logging) - even between nodes running in the same SolrCloud and/or on the same host. For instance one node of a SolrCloud might have org.apache.solr.cloud.overseer.SliceMutator which can be set, but no other instance of the same SolrCloud has that setting. Could someone clarify what determines which setting are available? Thanks
