Safepoint Bean?

[Hohensee, Paul]

I don’t know of any. Also, it appears that there are no uses of any of the HotspotRuntimeMBean methods in the JDK, so it could actually be removed! If you want to add its methods to a public interface, I’d create com.sun.management.RuntimeMXBean by analogy to c.s.m.ThreadMXBean and use the supported/enabled approach of *ThreadAllocatedBytes*. Needs a CSR, of course.

Subject: Safepoint Bean?

Hi there,

Is there a standard MBean (similar to GarbageCollectorMXBean), or other mechanism, that can be used to get safepoint statistics from Java (count, time, etc.)? I know it’s possible to get that info from sun.management.HotspotRuntime.java, but I assume this is not a publicly accessible API any more? Is there a standard alternative?

Thanks,

Tony
