【问题描述】:
我正在使用 DTraceAsmProfiler 在 MacOS 上运行 IDEA 的基准测试,但它失败并出现以下错误:
Exception in thread "main" org.openjdk.jmh.runner.ProfilersFailedException: Profilers failed to initialize, exiting.
at org.openjdk.jmh.runner.Runner.internalRun(Runner.java:228)

我的代码:
public class BenchmarkRunner {
public static void main(String[] args) throws RunnerException {
Options opt = new OptionsBuilder()
.include(CRHMBenchmark.class.getSimpleName())
.warmupIterations(10)
.warmupTime(TimeValue.seconds(1))
.measurementIterations(10)
.measurementTime(TimeValue.seconds(1))
.addProfiler(DTraceAsmProfiler.class)
.forks(5)
.build();
new Runner(opt).run();
}
}
我也尝试从终端运行它并得到同样的错误:
% java -jar target/benchmarks.jar CRHMBenchmark -f 2 -w 1s -r 1s -prof dtraceasm
Profilers failed to initialize, exiting.
[sudo: a password is required

以前有人遇到过吗?
【问题讨论】:
-
您是否尝试以提升的权限运行它(
sudo不需要密码)? -
我正在尝试
shell stsypanov@MBP-SERGEYT assembly-profiling-and-all-all-all % sudo "/usr/bin/java" -jar target/benchmarks.jar CRHMBenchmark -f 2 -w 1s -r 1s -prof dtraceasm The operation couldn’t be completed.
