re: monitoring performance trends we use a free option which is lightweight and works at collecting the general java stats info out of solr is using the sflow agent for java. in concert with a host sflowd setup you can gather the jvm and system stats in decently dense intervals (default is 30s) and then inject them into a trending/graphing system like ganglia or graphite
