运行jmeter的serverAgent源码报错：java.lang.UnsatisfiedLinkError: org.hyperic.sigar.Cpu.gather

报错

解决：

将 sigar-amd64-winnt.dll 放到 jdk/bin 下

如何拿到 sigar-amd64-winnt.dll？

下载链接：[https://github.com/undera/perfmon-agent/blob/master/README.md] ，可直接使用的 serverAgent-v2.2.3.zip，在 lib 文件夹里面拿到 sigar-amd64-winnt.dll

 

参考：（可以先按照这里的步骤尝试能否正常运行）
