: depending on the Solr version and on the servlet container. In some : cases the domain name is "solr", while in others it is "solr/". But we : also saw further inconsistencies. For example, we have 2 Solr 1.4.0 : instances on the same version of the servlet container, and one has : "solr", while the other has "solr/" domain name.
I believe the default naming is "solr/${corename}" -- but if you are seeing "solr" by itself in some cases that may be an edge case when using the legacy single core mode (not certain ... could maybe be a bug) there is also the "rootName" attribute on the <jmx/> solrconfig.xml setting which can override the defailt -- maybe some of your indexes are explicitly settting this to "solr" ? https://issues.apache.org/jira/browse/SOLR-1843 -Hoss
