That sample solrconfig.xml includes <jmx/>, but the 7.0 release notes say that is no longer supported. Should that be removed from the config?
"<jmx> element in solrconfig.xml is no longer supported. Equivalent functionality can be configured in solr.xml using <metrics><reporter ...> element and SolrJmxReporter implementation. Limited back-compatibility is offered by automatically adding a default instance of SolrJmxReporter if it's missing, AND when a local MBean server is found (which can be activated either via ENABLE_REMOTE_JMX_OPTS in solr.in.sh or via system properties, eg. -Dcom.sun.management.jmxremote). This default instance exports all Solr metrics from all registries as hierarchical MBeans. This behavior can be also disabled by specifying a SolrJmxReporter configuration with a boolean init arg "enabled" set to "false". For a more fine-grained control users should explicitly specify at least one SolrJmxReporter configuration.” https://lucene.apache.org/solr/8_7_0/changes/Changes.html#v7.0.0.upgrading_from_solr_6.x wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Dec 15, 2020, at 7:36 PM, Walter Underwood <wun...@wunderwood.org> wrote: > > Thanks.
