Measure cache misses in JVM

Asked 27/6, 2016 at 7:58 Answered 27/6, 2016 at 11:50

Is it possible to measure cache misses in a running JVM?

Even better, is there a way to get these metrics in JProfiler? Or any other profiler?

I have explored JProfiler options and haven't seen an inspection for this.

You could try Oracle Solaris Studio which also runs on Linux (but not windows) – Cadal 27/6, 2016 at 8:10

On linux you can use perf-map-agent which provides java integration for perf-tools.

async-profiler is another tool supporting perf events.

I guess it's not possible to use async-profiler for this on Mac OS X yet: github.com/jvm-profiling-tools/async-profiler/issues/182 – Cooperage 21/12, 2018 at 9:17

No, this is beyond the scope of a Java profiler.
