As of Solr 4.1 (three years ago), request rate information is available in the admin UI and via JMX. In the admin UI, choose a core from the dropdown, click on Plugins/Stats, then QUERYHANDLER, and open the handler you wish to examine. You have avgRequestsPerSecond, which is calculated for the entire runtime of the SolrCore, as well as 5minRateReqsPerSecond and 15minRateReqsPerSecond, which are far more useful pieces of information. https://issues.apache.org/jira/browse/SOLR-1972 Thanks, Shawn
