I filed https://bugs.openjdk.java.net/browse/JDK-8087107 and attached a
patch to the ticket that exposes some useful code cache stats as perf data
$ jcmd <pid> PerfCounter.print | grep -i "sun\.ci\."
At Twitter, we've found this useful for easy monitoring of code cache
activity, and would like to see this integrated into OpenJDK.
