有一些名为Intel Performance Counter Monitor的东西，可以为您提供事件的统计数据，例如;
EXEC : instructions per nominal CPU cycle
IPC : instructions per CPU cycle
FREQ : relation to nominal CPU frequency='unhalted clock ticks'/'invariant timer ticks' (includes Intel Turbo Boost)
AFREQ : relation to nominal CPU frequency while in active state (not in power-saving C state)='unhalted clock ticks'/'invariant timer ticks while in C0-state' (includes Intel Turbo Boost)
L3MISS: L3 cache misses
L2MISS: L2 cache misses (including other core's L2 cache *hits*)
L3HIT : L3 cache hit ratio (0.00-1.00)
L2HIT : L2 cache hit ratio (0.00-1.00)
L3MPI : number of L3 cache misses per instruction
L2MPI : number of L2 cache misses per instruction
READ : bytes read from memory controller (in GBytes)
WRITE : bytes written to memory controller (in GBytes)
IO : bytes read/written due to IO requests to memory controller (in GBytes); this may be an over estimate due to same-cache-line partial requests
TEMP : Temperature reading in 1 degree Celsius relative to the TjMax temperature (thermal headroom): 0 corresponds to the max temperature
energy: Energy in Joules

现在，该软件还可以选择从程序内部调用。如果在该程序中调用某些函数，它会为您提供这些函数的统计信息，如示例中所示。我的问题是所有的软件，库和代码部分都是用C ++编写的。当我在互联网上搜索时，一些人聚在一起，开了一个开源项目作为Java Performance Counter Monitor。但是，该项目最后一次更新于2011 - 2012年，甚至该网站都是在Sun下构建的，并不确定它是否可以在Java 8下运行。
所以我的问题是有任何性能分析程序或关于如何在我的Java程序中使用IPCM的任何建议吗？
