Hello,

You can find some information in the HotSpot specific 
MBean: 
http://www.docjar.com/docs/api/sun/management/HotspotCompilationMBean.html

However I am not aware of metrics you are looking for (Compiler queues 
length, proportion of compiled code)
I am using the compilation count (getTotalCompileCount) as a metric to see 
if the system is still in warmup state or in the steady state.
