Azul Zulu JDK 8 with Azul Mission Control doesn't profile methods


I'm using Azul Zulu JDK 8 (v1.8.0_202) with Azul ZMC 7.1.1 on Win10, and I'm creating a 20s Flight Recording of a running JVM. The resultant data displays various captured metrics (e.g. CPU Usage Heap Usage, Allocation etc) but no Method Profiling data. I've tried with both a Time Fixed recording and the Continuous recording - both have the same issue. The highlighted section in the following screenshot indicates where I'd expect to see method profiling data:

Is there some trick to enable this? I can't any reference to this in the somewhat sparse documentation.


Solution

  • According to Azul Zulu documentation there was a bug with Method Profiling in Zulu 8 fixed in Zulu8.38 (8u212).

    Please, try a newer version for Zulu8: https://www.azul.com/downloads/zulu-community/?version=java-8-lts&architecture=x86-64-bit&package=jdk

    Also, make sure you've enabled Method Profiling while starting recoding:
