The Costs of Hidden Logging
The story of a partially implemented logging facility in the JDK 8 backport of JFR (for which I was also partially responsible)!
The introduction of a throughput management mechanism in JFR allows getting fine details about the application behavior without the risk of being overwhelmed by the sheer number of JFR events.
The results of our preliminary tests of the setups previously completely unable to run with the allocation profiling events turned on are very exciting – JFR with event emission rate controller is able to provide a clear statistical picture of the allocation activity while keeping the recording size at a very manageable level thanks to the limit imposed on the number of captured TLAB events.
If you want to know what I spoke about in @jcon_conference in Germany, here's an interview I did at the @foojayio podcast:
