Java 8 如何使用uprobe跟踪OpenJDK热点源代码？

我试着按照老师的指示去做

在这方面,

我搜索了很多，发现它与libjvm.so有关。然而，我不知道下一步该怎么办

wxf@wxf:/home/wxf/adjustableMaxHeapSize_9jdk_prj/9dev$ find -name "libjvm.so"
./build/linux-x86_64-normal-server-slowdebug/support/modules_libs/java.base/server/libjvm.so
./build/linux-x86_64-normal-server-slowdebug/hotspot/variant-server/libjvm/gtest/libjvm.so
./build/linux-x86_64-normal-server-slowdebug/jdk/lib/server/libjvm.so

C++符号是二进制对象。你找不到次要的收藏。void AdaptiveSizePolicy:：minor_collection_begin的损坏符号名称为

root@wxf:/home/wxf/perf-tool/perf-tools/bin# ./uprobe -s p:/home/wxf/9dev/build/linux-x86_64-normal-server-slowdebug/jdk/bin/java:AdaptiveSizePolicy::minor_collection_begin
