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.
