Hi, The API admin/metrics <https://cwiki.apache.org/confluence/display/solr/Metrics+Reporting#MetricsReporting-MetricsAPI> in 6.x version of Solr seems to be very good. Is it performance friendly as well?
We want to use this API to query the metrics every minute or so from all Solr nodes and push to grafana. How does this compare with the performance overhead of reading JMX metrics via Jolokia? Rest API is surely easier to understand and parse. However it involves making a REST call that will pass through jetty, probably take up a thread for each request? etc. Is Jolokia lighter-weight in this respect? Some recommendation on this would be great. Thanks SG
