Thanks. I also just now found https://lucene.apache.org/solr/guide/7_6/metrics-reporting.html
I'm currently sticking to version 7.6 I've enabled JMX metrics and am accessing them via JmxTerm. There are indeed a lot, though filtering by key=value is easy enough. That being said, finding out what they mean is a bit harder. Also, it seems that even the most recent documentation is out of date. For instance here: https://lucene.apache.org/solr/guide/8_2/performance-statistics-reference.html#commonly-used-stats-for-request-handlers At the bottom there is mention of "avgRequestsPerSecond" and "avgTimePerRequest", which in fact do not exist anymore. I can see them on older versions of solr, but not on 7.6 And it seems nothing with identical meaning has taken its place. I'll make a separate question for that.
